Collapsible panels

[noirb]

I'm curious if it might be possible to support collapsible panels, similar to these ones in Blender:

It would probably only make sense to allow docked panels to be collapsed, and I think ideally it should be optionally enabled for individual panels.

I'll mark this as a feature request. Right now, setting a panel's Min Size Y value to 0 is the closest thing to this. I don't think this feature can be fully integrated without first supporting tabs on the left/right sides, though.

Thanks!

Yeah, I can think of a few ways to collapse/expand a panel, but determining when to spawn the < button to let the user re-expand a collapsed panel and docking it to the adjacent edge/panel seems a little less straightforward. Would be easier with an OnPanelResized event to, e.g., disable any panel less than a few pixels wide, but I'm not sure how hard it could be to dock a non-Panel object (or is there a way to create alternate Panels which can work with the docking system but don't include any tabs, etc?).

Only Panels (GameObject) and PanelGroups (plain C# objects that represent horizontal/vertical layout groups) are dockable. Creating panels with no tabs will require modifications because empty panels are destroyed as far as I remember.

I can't give this feature request any thought for the time being so I may not be able to give you useful insights about how it can be implemented.

I know this has been out there a long time but I would also find this feature useful
