Draggable
A free-floating panel that can be repositioned anywhere on screen by dragging the grip bar.
Basic
Click "Show panel" to mount a draggable panel. Drag the grip bar to reposition it anywhere on screen.
With handle label & actions
The handle slot adds a title to the grip bar. The actions slot places controls at the right — drag events don't start from action area.
