I was following your tutorial:https://youtu.be/vn2xIVoNY04?t=383
And I can not replicate it.
I created a 2d array in adaptive mode. The corners, the top, the bottom and the sides can be easily positioned. But I cant manage to make the default element follow the top and bottom element span. I tried to add a padding calculated from the difference of width between the two elements, but as I use the adaptive mode, the width of the top element is altered when the Raiclone object is created.... and in your exemple, your setup is way simpler... So what am I missing?
I have been pulling my hair for a couple of hours on this setup which should be super easy.
