Is there a UI Control for collapsible (accordion) container

Question

Hi,

I'm trying to find a control or a way to have a container open or collapse if you press on the title bar like this: https://en.wikipedia.org/wiki/Accordion_(GUI)

The Godot inspector tab in the editor uses this a lot, but I can not figure out how to do it in my game other then custom build. Is there some control or something I overlooked?

I tried a custom solution with a VBoxContainer containing a button and another container.

VBoxContainer
   Button
   VBoxContainer
        Label
        Label
        Label
    Button2
    VBoxContainer2
        Label
        Label
        Label

I added an AnimationPlayer to animate the rectscale.y of the inner container.

func _on_Button_pressed():
    if(container.rect_scale.y == 1):
        player.play_backwards("Accordion")
    else:
        player.play("Accordion")

It has a nice animation but the ui elements following the shrinked container did not relocate leaving a blank space between the button and the next ui elements. Only if I hide the inside container, the ui updates its positions, but then I can not animate the accordion.

func _on_Button_pressed():
    if(container.visible):
        container.hide()
    else:
        container.show()

Any chance you found a solution for this? I want to do exactly the same in my UI.
