Hello, Matej,

The TreeView design is to expand based on the content. If we set a fixed width to it, it will automatically show a scrollbar. The width can be set with a className and CSS:

Please let me know if you need additional information on this matter.

Not sure I understand. Even in your example all sub-items are cut and the scroll is working only for first level items. See attached screenshot.

Hello, Matej,

My apologies, indeed the items are still cut.

This can be resolved with the following CSS:

.k-treeview-item .k-animation-container{
  overflow: inherit;
}
This is the updated example:

https://stackblitz.com/edit/react-haaavq-lvxqpu?file=index.html

Everything seems visible now.

Thank you. Is this going to be part of your styles in the future or are there any conflicts with existing styles?
