Hi Mario,
You can use CSS Flexbox (via Extended Properties in Xway) to arrange boxes side by side.
See this thread:
https://discourse.softpress.com/t/boxes-inside-boxes-fw-float-left/
(Search for “flexbox” after clicking on that link.)
The next version of Xway will support flexbox directly (via the Box Inspector) - it’s something we’re currently working on.
