Control the expanded/collapsed state of treelist items
I would like to start the tree grid with all rows collapsed. At the moment I can do this only through load on demand.

Hi Team,
I would like to load Treelist for Blazor by default in Collapsed state.
Also looking for functionality like expand all / collapse all.
Let me how can achieve that?

Hello Al,
You can see an example of how to collapse and expand the items from code from our documentation.

So, I installed this version. How can I control state of items?

Hello,
I am attaching to the end of this post a potential workaround that can help start a treelist with all items expanded - to see this work select one item from the treelist, click the button below it to see the second treelist populate with some data.
This is not a feature yet, it relies on re-rendering the treelist by toggling its visibility with an if-block, and that having all data items with hierarchical binding will start them expanded at the moment. Such a workaround should be replaced with a real feature when it becomes available and I cannot guarantee it will work in all cases.
