Collapsible dysfunctional after remove_children()

[tibor95]

I am trying to remove all children and immediately add new ones into Collapsible. I am doing only removal now, and the collapsible changes into label(??) or just empty space of 1 row.

Here is example with 2 former Collapsible, one was collapsed, the other was not.

None is clickable.

I am doing this:

current_collapsible = self.query(Collapsible)[0]   
current_collapsible.remove_children()

No traceback or any other hint.

You should probably explain why you want to do this, as it feels like an odd requirement.

However, any of these solutions should work:

• Replace the Collapsible as well.
• Add a ContentSwitcher inside the Collapsible, put your content in there.
• Put another container inside the switcher, and replace the content in that.

The reason it is breaking, is because the Collapsible has children of its own, and you are removing them.

I think this will remove all the children.

await self.query_one("Collapsible Content").remove_children()

However I would consider the other solutions first.

There will be a thread with some sort of query retuning 0-10 of items (run periodically) and we need to update the content of the Collapsible.

re "another container inside the switcher" - can I just put Horizontal directly into Collapsible and update content of that (remove and add widgets)?

OK, so I opted for replacing entire collapsible - if there is a change. So far it seems to work nicely
