+
+ A container that can be expanded/collapsed, with a title that can be filled with controls, such as buttons.
+ The title can be positioned at the top or bottom of the container.
+ The container can be expanded or collapsed by clicking the title or by pressing [code]ui_accept[/code] when focused.
+ Child control nodes are hidden when the container is collapsed. Ignores non-control children.
+ Can allow grouping with other FoldableContainers, check [member foldable_group] and [FoldableGroup].

+
+
+
+
+
+
+ Adds a [Control] that will be placed next to the container's title, obscuring the clickable area. Prime usage is adding [Button] nodes, but it can be any [Control].
+ The control will be added as a child of this container and removed from previous parent if necessary. The controls will be placed aligned to the right, with the first added control being the leftmost one.

+ Background used when [FoldableContainer] has GUI focus. The [theme_item focus] [StyleBox] is displayed [i]over[/i] the base [StyleBox], so a partially transparent [StyleBox] should be used to ensure the base [StyleBox] remains visible. A [StyleBox] that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a [StyleBoxEmpty] resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.
