If you already have a layout container with content in it, you can edit, move, or duplicate it without deleting the content inside of it.
Sign in to your site and go to the page that has the Layout Container on it that you would like to edit.
On the left-hand side, turn on Edit Mode.
In the right-hand corner of the Layout Container, click on the gear icon.
Choose Edit, Move, or Copy.
Choose Edit to change the Layout Container's layout.
Choose Move to move the Layout Container to a different page.
Choose Copy to duplicate the Layout Container on the same page.
Confirm your selection.
