Feature request: collapse/expand event on wa-tree

[steunix]

Hi all,

I'm using a wa-tree with a considerable number of wa-tree-item (about 2k). I need to save expanded/collapsed state of each wa-tree-item (in localStorage), and in order to achieve that I need to add a expand/collapse event listener for each item.

What about having an event expanded/collapsed event at wa-tree level too? That would make things easier with only one event handler instead of one for each child.

Isn't the DOM limit 2k? Your one tree is taking up the general entire ODM memory capacity?

Total DOM Elements | ⚠️ Warning at ~800 nodes
❌ Error at ~1,400 nodes | Rendering, memory, interactivity
Maximum DOM Depth | >30 levels deep is considered problematic | Style recalculation, layout thrashing
Max Child Elements per Node | >60 children per node can trigger layout issues | Reflow and repaint complexity

Hi,
i'm not hitting any browser performance problem, the memory footprint is less than a common GMail page. The 2k nodes is a sort of exception (admins having full view on hierarchy), but nevertheless.

The wa-expand and wa-collapse events bubble, so should arrive at the wa-tree ancestor. Does installing a single event listener at the wa-tree level not work?

Man... why didn't I think about it? Thanks!
