Rearranging Elements
Moving containers moves their children. Open Structure , expand source/destination branches, drag the row to the intended insertion point, and save. Indentation shows parent relationships.

On the canvas, select and drag using the element's handle, follow a valid insertion indicator, and confirm placement in Structure.

The new parent changes layout context, potentially changing dimensions, alignment, or spacing without altering local values. Invalid nesting prevents drops. Flex reversal/grid placement can display a different order from Structure.
See layout controls or Copy and Paste for cross-document movement.
