We have created some reusable components for our site and have hit a problem when trying to add more than one instance of these component to a page. This is an issue because Sitecore needs the placeholder key to be unique. Does this mean you can never add more than one instance of a sublayout with a placeholder on to the same page?
Example:
Two column sublayout - placeholders 2column-col1 and 2column-col2
Three column sublayout - placeholders 3column-col1, 3column-col2 and 3column-col3
On the page add a two column sublayout, a three column sublayout and then another two column sublayout
There are now 2 placeholders with the name 2column-col1 and 2 placeholders with the name 2column-col2
Is there any way around this? We thought of dynamically creating the placeholder key in the user control code behind but this causes problems if you want to use placeholder settings.
It seems that it would be a common thing to want to do. Is there a workaround?
What you can do is dynamically create the placeholder keys to get the desired functionality and then manually create 5-6 placeholder setting items and duplicate the settings for all of them. I have done this in one project and it works well even though it's very ugly.
If you are using sitecore 6.4+ you might even be able to use cloned items to create the placeholder settings. This way you will be able to control the allowed sub-layouts from the original item and all the rest will just inherit the values.
Hope that helps.
I believe this is a duplicate of your SDN post, but for reference I will link my blog post (with prototype solution code) here as well.

In Sitecore 6.3.1 there is a setting in web.config
<!-- DUPLICATE PLACEHOLDERS
Indicate whether to process duplicate placeholders
Default value: false
-->
<setting name="Rendering.ProcessDuplicatePlaceholders" value="false" />
I think this setting is available on all versions of Sitecore 6.
You should give it a try and change it to "true".

I am using Sitecore 8.2 and I have many items, created from the same template. Though I have set the renderings in the standard value of the template for common components like header and footer, but want to make sure that these renderings can't be added twice.
Can we achieve this? If yes, what the ways?
If you do not make the rendering available to be added to a placeholder, then no author will be able to select it from the Component selection dialog in Experience Editor.
The "Allowed Controls" list is how you will specify which controls are allowed to be added to a given placeholder.
If you mean you want authors to not add the rendering twice, then probably you can add a processor into < insertRenderings > pipeline. Check if that helps.
I am creating a Sitecore MVC site for a client and I need to create page that will list news articles for the company.
So far, I have created items that use a shared data template called “Article,” and I also have a sublayout (a view rendering) called “Article” that will display these items.
For the list itself, my plan was to create another component (a sublayout) call “News_List”, and to put a placeholder in it called “List”.
My question is this: can I allow the author to insert articles (e.g., N items of type “Article”) into this placeholder via the page editor?
Will SC allow you to insert multiple instances of the same component into a placeholder? Will this break anything?
I believe this is a pretty common question but I have not found a definitive answer. Thanks in advance…!
You can insert as many components (of the same type) in your placeholder as you want.. Just make sure to put the placeholder settings correctly and give it a decent name (not just "list" ;))
But are you sure you want to do this? Your editors will manually need to create a list of components for each article they want to add on the page. Doesn't sound to be very user (editor) friendly.. Maybe you should consider creating a list component that can get a list of articles as a datasource and show those. Or even select them automatically (but that might be not according to your business case)..
Yes, authors can add multiple instances of the same component into a single placeholder.
Assuming that the code of the component doesn't do any stupid things it's absolutely ok to do this.
So I am rather new to sitecore, and it's a topic that wasn't covered during my training. My questions is just to help point me to the correct term, or documentation on a method to do the following.
I have a definition item, with a ton of field groups, what I want to do is something like:
if Value of Field X is "yes" then collapse/hide Field X or Field Group X.
Does that make sense? Is it a validation rule? or some other kind of rules, is it a workflow I need to attach? Do you place it on just the field I want to hide, or the field that triggers the action?
I appreciate any guidance.
There is nothing out-of-the-box in Sitecore to achieve what you want but there is no reason you cannot create a composite custom field type to do this. The following articles will help you achieve this:
Creating a custom Sitecore Field
Getting to Know Sitecore: Custom Fields, Part 1
Create a new control, inheriting either from Droplist (if the comparison of the value is to be text based) or Droplink (for comparison of ID). You could add a parameter in the Source field of the control to specify what the values that trigger the hide should be.
The underlying control in the Content Editor is just a standard HTML select element. Add onchange events to the control and add your Javascript handler to hide the other controls. Since I could not find a way of adding additional custom css classes to the Sitecore controls, it would be best/easiest to hide all other controls in the same collapsible group after you control. This would mean you would need to group your controls better (or logically at least).
The Javascript will be something like this (the Content Editor uses the Prototype JS framework):
if ($(this).getValue() == 'no') {
// find the parent container of this control and then hide all the next siblings in the same group
$(this).up('.scEditorFieldMarker').nextSiblings('.scEditorFieldMarker').invoke('hide');
}
You can test this by running the above in the console, change out the keyword this with the id of your field, e.g. $('FIELD2292054').
What I am not sure about is how to trigger the hide on initial load, i.e. when someone returns to an existing item, it may be possible by adding to one of the pipelines, but would be better using a JS solution if possible. I'll have a think about this and get a proper code sample up over the next few days.
EDIT: You can add an event handler to sc:contenteditorupdated to handle the content editor being rel-oaded.
document.observe("sc:contenteditorupdated", myFunction);
I wrote up a blog post and put the code on GitHub if you are interested.
Not sure if you have come across Andy Uzick's this blog post.
He wisely talks about hiding fields in the Content Editor and has also created a Sitecore Module called Hide Field Template Extension which is hosted on the Sitecore Marketplace with the full source code to extend.
After reading through and trying the extension, I do feel that it will not completely resolve your issue (how you have described it in the question).
But it will give you:
A mid-term solution to hide a few unnecessary field that some content editors would not like to view.
Fields that are only required by administrators for admin purpose - to de-clutter these fields could be hidden.
Just one thing to bear in mind that it mentions in the requirements Sitecore 6.5 & 6.6. I have not tested it in Sitecore 7. If you are using Sitecore 7, which I think you are, one could modify the source code and make it work for Sitecore 7.
Have a look and share your findings.
Happy Sitecoring!
I would like to know how do you do pre-loading of components in sitecore 7.1?
What I tried so far:
Create a standard value for the page.
Then modify the presentation details of the standard value.
Then add components that I want preloaded in the page.
Then create a Branch for the page.
Use the Branch to create the page.
This works fine except when I add new components in the page's standard value, all existing page is affected with my changes.
What I need to know - is there away that the old page is not affected by my changes in the standard value?
Is there a way only the new page that I create is affected when I modify the pre-loading of components in my page?
Your input is appreciated.
There are few things one should consider:
If there current Sitecore installation is upgraded from 6.4 or prior version to your current version; the item's layout deltas might be an issue. You will have to check the raw values of the Layout details field and figure it out.
Any changes made on the Layout Details on Standard Values do get cascaded down to the items created from that specific Template.
If you don't want these changes to get inherited try multiple inheritance. And change the template of those items created.
Lastly, if the above doesn't work, try creating a new template with the changes you want and change the Template of those items created.
Hope the above helps. Share any further questions you might have or even if the above haven't answered your questions.
Happy Sitecoring!
The main purpose of __Standard Values is automatic update of existing items.
In this case, you should not configure the item's layout in the __Standard Values.
You need to use Branch and configure layout in the Page item instead of __Standard Values.
Before digging into my explanation i will summarize my question:
How do I provide the user (editor) with a user-friendly possibility to select a datasource item for sublayouts that are preset on the standard values?
My situation is as follows:
I have a page template, with pre-defined layout on the standard values.
Let's say the layout consists of:
one placeholder "wrapper"
one sublayout "content"
This sublayout is pre-defined on my page template, but can also be placed in the placeholder using the Page Editor.
It needs to have a datasource item that defines a Title and Body value.
Now, if a user adds this sublayout to the placeholder using the Page Editor, he will get a nice interface to select or create the datasource item (see screenshot).
However, if the sublayout was pre-defined on the standard values, it will be added without datasource (I can't pre-set the data source in the standard values because it's still unknown by then).
At that point there seems to be no way to get to that nice interface for selecting or creating a datasource item.
Ideally I want to be able to add a field to my template that can hold a datasource item which the user can select/create using the nice interface. I looked at the datasource field type, which could be an alternative, but it's still not exactly what I want.
Bare in mind that the content sublayout is just an example.
I understand that in that specific case I could solve it by always adding a title/body field to the template which hold the values if there is no datasource, but for my real world problem that won't suffice.
I don't have a whole lot of experience with the Page Editor (with the new way of working with it) so I would like to get some advice on this subject.
According to what you said here:
Ideally I want to be able to add a field to my template that can hold a datasource item which the user can select/create using the nice interface. I looked at the datasource field type, which could be an alternative, but it's still not exactly what I want.
It seems you want an intuitive data source selector interface in the CMS shell similar to the Page Editor-based UI.
Quick answer: Simply put, there's nothing that does this for you in Sitecore.
Longer answer: There are still some options for you, e.g.
Define a global "dummy" data source and set that to be the data source set in in Presentation > Layout Details of the template's standard values. So every time you create a new page, it will always point to that dummy value to show something.
From here you can do a few things:
If the user must use the shell UI and not Page Editor, they can simply create another data source item for the specific page and update that page to point to it using the existing native interface in Layout Details.
Another option is to write an event handler, say for item:created or similar that when you create an item, auto-create a corresponding data source item for this specific page (whether this auto-created item be a sub-items or global item...) then programmatically set this to be the data source. A similar concept is shown in this video by Nick Wesselman: http://www.techphoria414.com/Blog/2012/May/Sitecore_Page_Editor_Unleashed
