Is there a way to rename the div items on the left sidebar?

How do you rename the names of the tree items like the divs or labels to the name you need?

Each element in the left pane has a name that identifies what it is (bloc, row,column). You can’t change them but you can add a unique id. Click on the element in the left pane and at the top of the right pane (inspector) the first panel is ID. You can give the element a ID. This will give the element the name, lets say Bloc #menu or Row #header.

Hope this helps
