use the stack element: +more → +stack
with it you can put elements above one another inside a single row
preview pages cannot be accessed when you're not logged in as an admin, so i cant view your link
I'm able to drag in several images in the same 'row' but not text boxes
not sure what you mean here. texts and images can be next to one another in a row.
what does this all have to do with overlays?
Do you mean this?

or do you just want to overlap elements?
if you want to overlap elements:
do this:
if your row has a custom row height (right click row, set custom row height) or browser height (right click row, set custom browser height), then all elements within that row can be placed anywhere, overlapping each other.
or do this:
right click an element and click "position freely"
