WEBCON BPS 2024 introduced different kind of form templates:
While this is great for WEBCON BPS 2024 users. You can already achieve something similar with a little HTML field in previous version. You could even make it dynamic. If one tab needs a lot of space you could hide the right area, if this tab is activated.
There's one exception, I didn't had the idea to with the "one column" option where there's a padding on the left and a right. Maybe someone else takes the time to fiddle around with the css.
You can read up on it in this post: Revised changing left/right layout
This is the revised version because the version in 2021 didn't use HTML fields as they haven't been available.
