Use :

Drag & Drop as you would with any Panel widget, populate with children, and profit. Simple as that.

Details :

• Select either Vertical or Horizontal layout.
• For each re-sizable children, ensure it resize dynamically elegantly. e.g use ScrollBox, ListView, or clipping if necessary.
• Like in VerticalBox etc, each children is either constant size (AUTO), or take place according to a to a size coefficient (FILL). Setup the default layout using theses rules.
• One can set a minimum size in pixels for children.
• Customizable Style and Thickness for the splitter lines (separators handles)
• Unreal 5 : minimum pixel size is now customizable per children.
