Treeview structure changes after kendo UI version 2024.1.319 March 18, 2024

[Gkitsos]

Hello, I have noticed some changes on the structure of the Treeview component after version 2024.1.319 March 18, 2024

Classes like k-group and k-in seem to have been removed completely

For example, in previous version, the structure of a Treeview component would look like this:

<ul class="k-group k-treeview-group">
	<li class="k-treeview-item">
		<div class="k-treeview-top">
		         <span class="k-treeview-leaf k-in">TEST STRING</span>
		</div>
	</li>
</ul>

while now it would look like this:

<ul class="k-treeview-group">
	<li class="k-treeview-item">
		<div class="k-treeview-top">
			<span class="k-treeview-leaf">
				<span class="k-treeview-leaf-text">TEST STRING</span>
			</span>
		</div>
	</li>
</ul>

On release notes, I did not find any particular reference on these classes being removed

So my questions are:

1. Have they been removed widely?
2. Are there any other components that may still use these classes?
3. Is there any form of documentation that contain these changes?

Thank you in advance

Hello, George,

The changes are part of an internal effort to unify the rendering across the Kendo components. 

1. Yes, those classes are removed from the TreeView and in every component that uses the TreeView internally.

2. As a result of the effort, those classes shouldn't be used in other components.

3. We are preparing an article in our Backwards compatibility section for 2024 breaking changes, which will be live for the next release in November.

Let me know if you have any further questions.

Regards,
Martin
