Hi savio982
Thanks for giving Ultra a try 🙂 Page Builder supports full width stretched rows. To make use of this functionality, edit any row by clicking the wrench icon on the far right > Edit Row > Row Layout and set the drop down menu to Full Width Stretched.
I’ve made a quick video covering these steps. It’s my first ever public screencast, so not exactly a polished product 🙂 Hopefully it helps explain this Page Builder functionality.

Sound is unfortunately quite soft so please turn your volume up to hear.
