Save complex placeholder

hey guys so as part of today's topic will be going over site code dynamic placeholders and we will see like how it is different than the regular placeholders and we'll also see like what are the scenarios when like we should go for where we can actually use static placeholders and the use cases where like we we have to go for you know dynamic placeholders so let us consider a very simple use case where we have you know a one column layout so let's say we have a page then in that page has an header then it has a footer and then it has a body body section and inside the body section you can think of like you know it has we have basically integrated a one column layout and then inside it one column layout we have one place holder and that placeholder is like agenda you know a generic placeholder and we can use that placeholder to to add as many components we want right so if I cou if I want to if I have to show you then you can think of like this is our standard right then this is a very basic layout file which I have here so we have a top placeholder then we have Center placeholder and then we have a bottom placeholder right so this is the this is what we have on the on the layout file and the use case which I was talking about like we have a one column frame right and that one column frame has you know it's a container which is which has a main content placeholder so what this does is like it let's see if you have to configure let's say if you have a very basic article page which has had a footer and then main body then what we can do is we can we can use this standard layout standard CSS tml as an layout and then we can use PS top to configure your header then we have PS bottom to configure your footer and then we can use this PS Center directly or in case if we want you know if to have some kind of wrapper defined for this PS Center then what we can do is we can have a you know a separate section or frame which in this case what I have done is we have a separate frame created for that and then inside this frame you can have as many rappers you want whatever whatever you want to define that you can do that and then in this section or frame you can have your second level place all right you know placeholder key you can define there and then finally you can use your pH main content to configure as many models you want so this is this this is the use case number one which is very pretty straightforward and there is no issue absolutely no issue with this kind of approach so in this case ultimately what happens is you have your header you have your footer and then you configure your one column frame to your you know to your Center placeholder and then finally in order to configure what different modules you have onto your page you can finally use pH main content to add as many components you want and any number of times so that was the recap second use case which I really want to talk about is let's let's take an example you know where we are talking about a generic page right and that genetic page is we can consider that that Cedric page is is having a two column layout so when we talk about two column layout so we can just again we can think about we have a page it has an header it has footer and then on the on the body section we have you know left left left hand side component we have and then we on the right hand side also we can have some some more components needed to type so in this case if we before we talked about even dynamic placeholder let's see the problem which we are going to face if you go with this kind of approach right if so what I am going to do here is let me go to site core and then this for instance which I have normally I use it for my testing so what I'll do is I'll just create another page a few more pages edit it there so let me just create page three right so this is a very generic page template which I have created now from here if I equal to publish an experience editor so yep before this that opens I'll let me just show you the presentation also of that generic base template still it's loading so let's just give it a minute so it's a basically there is nothing there is nothing fancy on this presentation it's it's very basic presentation which what we have there it we have had out then we have footer and then we have you know on center of placeholder we have configured our two column and that two column frame or section has again two more placeholders on it left and right so yeah let me mean way let me just show you how that placeholders looks so we have this two column frame where we have you know placeholder and then another placeholder with a key left and right on it so this is pretty basic placeholder let's see what's going wrong it's still loading okay yeah so the page is now open so now if you see like we we have these two place so we have you know we have these two components which is which is the default component now let me just see like let's say if we if you want to add another two column layout and then for that two column layout again if you want to have two more components attitude right right so what I can do so before that let me just show you how the presentation looks so if I go to final layout so it's had we have had our we have footer right so we have added we have footer and then we have I was talking to you I was I was mentioning I mentioned before that we have this PS Center and then for this PS Center basically we can have either your you know your section or a frame kind of stuff so that's the reason I have this two column frame configured to your PS Center placeholder and if we go to a two column frame then that frame again has two more placeholders left and right so this is basic right so now from this point let's say so this is fine right so I can see we have two volume frame here and then on the left hand side also we have one component in the right hand side we are also we have another component so now let us take an example we want to add one more you know a two column frame right so that I can have two two column layout for my other section also and I want to add two more components there so with with this approach if we go so let me just go to my es Center and then let me add one more two columns you know frame they're not section whatever you want to call it so once I selected two column frame now you can see as soon as I added another two column frame I I get the same data source yeah right so know more about our packages offers was the was what we had from the first section or from the first two column frame and as soon as I added the second a two-column frame I got the same data source now from this point if let me just save this thing and go let's go to presentation let me just refresh it doesn't make any sense so if I go to page 3 presentation details and if I go to fine yeah Oates right so if I if you see in the final layout what we have we just have another section got added which is no column frame so right we know as we we already had its header 2 column 2 column frame RTF RTF again from for the left and for the right and then footer hasn't player as an bottom placeholder for that but as soon as I add another section that is to bottom frame here I get this thing but there is no there is no change on the letter so it is still you know auto populating the same over data stores which is which is there before as well but this is not something which we really looking for right what we are really looking for is we need a flexibility where in like as soon as we add another frame and the section and that section we should be able to add different kinds of you know components with different data stores so it's not necessarily that we whatever components we have added in the previous section we rewrite we will add just those components again and again so we need we we need a flexibility to add different sections and then add different kinds of component with a different data source as well so in this specific case if you see because in this specific is way data where Sitecore is failing on in terms of placeholder mapping is like side code is not able to map that for which placeholder for which component and this placeholder it should it should get mapped right so that that kind of mapping is is something which is which is missing in this specific model so now in order to fix this issue what we can really do is if you side could actually introduce a concept of psychic or you know dynamic place order which is now integrated with side Conine which is now out of the box so what we can do is we can instead of using the regular placeholder we can replace this with dynamic placeholders so what happens is in case let's say if we have something very static right so as I mentioned my first use case was was was very static in nature where I added like one header footer and then one big content and inside that content only I would just keep on adding other other components right because it was very basic but now in out the you know the use case which you have taken next it had a different section or different frame and at a frame it said we we we are looking for some kind of flexibility to add different data source item and the frame also we should be able to duplicate so it's not it's not right at that frame let's say if you have used two columns frame once in a page which we are not able to use the two columns frame a second time in in the same page with a different data source right so we should we should have still have that flexibility that we should be able to add the already existing frame into the page again with different data source for different components so that that is what we are looking for and that is the problem which is solved by psychodynamic placeholders so now what happens is in this case we can just change this with dynamic placeholder okay and let me replace this with this and then let's go to standard and then what I'm going to do is I'm also going to change mass Center placeholder with the dynamic placeholder so that because ultimately the frames which I am going to add at that frame I'll being for inner tube is you know injected frame I'll be using PS centered so and there would be multiple frames which I want to add into my page so that's the reason I want to have this dynamic placeholder for PS center so that even the center can also be you know duplicated so now once we have these changes here so now my PS Center placeholder is also dynamic placeholder and my Mukarram frame is also dynamic placeholder which gets you know appended with with a different grid and that face ID code basically identifies each placeholder so it's not like it so there is there is a way to basically identify each placeholder under specific section or frame right so basically we have something to identify a token oh that yeah this is the unique identifier for this particular frame so I have a site code knows that for this particular placeholder it has to add this particular component with this data source so there is as long as there is something to identify I could but that was that at identification was missing in case of regular placeholder so now let me quickly publish these two changes so if I just go ahead and publish and then let me also go ahead and publish to column frame yeah the publish is all done so now what I am going to do is let me refresh it and go to generate page page four okay and let's go to experience and dynamic dynamic placeholders is something it is very specific to experience a writer because it will not be you know it it will not be very easy for the content authors to add different components using dynamic placeholder because it actually generates a grid which is not something which can be and can be you know scanned in others can handle it so that's the reason dynamically whenever we deal with enemy placeholders it it all comes why experienced editor and then in case if there is something very static in nature we can always go ahead with the content editor we don't really need to go for the experiencer interface for that okay so no so now we what we have here is we have created another page for which is again of generic page type and if we click on that what we see we have a centered placeholder which is again a dynamic place all to know which means I can add as many components using this P under this PA center because this is also no or dynamic placeholder so if I click on this ad here it gives me a flexibility to add as many components say I want but for this PS I entered the only allowed control was to column which is which is nothing but a section or frame you can think of so if I select this one let's click on select so what this does is like we have had our we have footer then under the body section we have this PF Center so under PS enter what we are trying to do is we are trying to configure a two column frame because that coop two column frame has left and right placeholder on it so I think in the page is still loading page is still loading sometimes okay so now what we can see here is we have left we have cried which is again part of your if you see there like it is all part of your two columns right because under two column only we have these two placeholders so now what I really want to do here is let me add a component so on the route control which is set for pH left placeholder is RTF so let's go ahead select it and then you can specify the data source for it as well fine so the next step would be to go to the right place holder which is again part of your you know two columns frame so just click on that click on RTF and select and then you can specify you can specify a different data source for that so in this case it is so much yeah right so now here you what you can see here is so far we have added under took under center so if I have to correlate so what we have done here is under this PA Center we have added two column frame which has a keen to more placeholders and we have configured two different components on left and right here now so this is this was fine even you know in case of if you go for regular placeholder also but now again the problem is let's say we have to add another instance of two column on the same page right because it again has you know left and right so because that was making it difficult to identify that which you know first of all which to column and then which to column which left and right exactly it has to configure it has to identify the data source so now as we able as I may already seen like we have replaced that Center placeholder to a dynamic placeholder so in this case if I want to you know let me just go to you know be a center and let me add another to column right because this P you just remember this PA Center is now our dynamic placeholder which means it can we can have as as many frames we can add here with different data source so I added another two column instance here and now if I go here if I can click on this I select this now we can have a different data source for that so let me just select this one and if I go on this click on add here and now select RTF select that it is so whatever you want maybe personalize that yeah whatever it is right so now if you see if you compare this page with what we had before as soon as we added two different components we had the same you know same data source added for for both frames like up no frame one and frame two basically the same data source we had there but now if you see after adding this dynamic placeholders we record a flexibility know we had this facility to add different data source for different frames so now even even if if you want to add multiple instances of the you know of two column and then you want to have a different component to your left and right then you can easily do it via tandem place notice so now if you see the data source is completely different than what we had on first instance first first instance of two column and then second instance of to column right so that is that one is we we get when we go for denim placeholders and then we have to talk about the use case variable in VN where we should go for you know what are the use cases where we should go for static placeholders and use cases via dynamic placeholders are more helpful so the answer is where you see the page is more static in nature and then you really need you don't have this kind of you know set up where under one place order you have another place you under one place order you are actually trying to configure one more kind of wrapper which has again set of different placeholders so if you have this kind of requirement then definitely it is not going to help you if you go for regular placeholders then you definitely have to you know go for dynamic placeholders but if your page is very static in nature and doesn't have a very complex placeholders hierarchy then maybe it just has an Hatter and footer and then one big placeholder big container and then in title container you can add you can just dump all your components with different data source definitely go for your regular placeholders you really don't need a dynamic place so let's there but yes if you are placeholder hierarchies to complex in nature it is higher acute the IQs there at least and then again the hacky in the form like you have one page you have one page then we you configure kind of wrapper and that wrapper has again set of different placeholders and you want to again you you know you want to configure it multiple times down to in your page then at that point of time it is very much required to go for dynamic place holders because then because if you go for a professional turn side code will not is will not you know not be able to identify that which placeholder than which particular trapper and place alright it needs to use to configure the data source for that which which makes it very much easy in case of dynamic play set up it because it because it generates the Kuwait which which helps ID code which is identify each and every place holder when like it has to configure that component so after adding these two rappers and then with two different components also if we if we go back to site core just let's go back to site koi and just see how the presentation look for this particular page into presentation details so let's go to find see if what sure if I have saved it so now it is saved okay let's go and let's go to page four presentation details right yeah so now you can see here what we see like we have a different grade which is attached to a each place component right so basically this way side core is able to identify that you know this particular component has to use and then this is the quit for that so this is basically a way for site code to identify that which component has to which place to write as to Iancu and configure the component with a different data source so I think this I'm particularly you some of you might already know about that in placeholders but sometimes what I've seen is we know about anomie create sort of but when it come when it comes to you know actually knowing how exactly it works inside code we sometimes struggle so that's that's the whole point of having this topic as part of today's session so I hope you liked it and thanks for watching and if you have any questions any feedback please please you know feel free to ask it and thanks for your time have a great day
