Hi Tim,
I tried that one as well, but for me it causes excess space in other places of the website… I never got it right.
Here a link to another post that I made on this: New - unofficial - feature: TABS - Hide/Show multiple blocks horizontally - #80 by thijs
In that post you see a screen print of the inspector showing the excess space is caused by something called: <div class="extra-div" style="background: rgb(255, 255, 255); height: 470px; width: 100%;"></div> == $0
Next to removing it entirely, a second best would be to change either the background color or the height. But I don’t know how.
