You can delete all but the last layout part from a layout and the objects it holds.
1. Select and drag any objects you want to keep to another part on the same layout.
2. Click the part label with the arrow pointer, then press Backspace or Delete. You can undo this action.
Note This method only works when there is a part below the one you want to delete.
1. Select the part label with the arrow pointer.
2. Press Ctrl+Backspace (Windows) or Option-Delete (macOS).
FileMaker Pro Advanced deletes the part and enlarges the part below the deleted part to make space on the layout for the retained objects.
