When this returns true you need to: a) call SetDragDropPayload() exactly once, b) you may render the payload visual/description, c) call EndDragDropSo

We don't use BeginDragDropTargetCustom() and duplicate its code because: 1) we use LastItemRectHoveredRect which handles items that pushes a temporari

Lock horizontal starting position + capture group bounding box into one "item" (so you can use IsItemHovered() or layout primitives such as SameLine()

Tip: To have a list filling the entire window width, use size.x = -FLT_MIN and pass an non-visible label e.g. "##empty" Tip: If your vertical size is
