TreeView - collapsed nodes by default

[sprogs]

Hello,

I'm trying to create a tree by generating UL and LI elements, it works great.
However, all nodes are expanded, I would like to add entire branches collapsed by default, how can I do this?
I do not want to use JQuery as much as possible, I create items as HTML or JavaScript elements.

I tried to set the class to empty and hide the subtree by default but it does not work well.

I know that there is an 'expanded' class, but I have not seen a similar 'collapsed' class that would solve the problem.

Best regards

Use attribute data-collapsed="true" for li

[sprogs]

it works great, thanks

best regards
