I have three boxes, one located next to the other.
The last two boxes are only visible when the user who views them meets a certain criterion, if he does not meet it, they are hidden.
The problem is that the first box in the second row is stretched to try and take up all the space previously occupied by the two boxes, but I don’t want this to happen, I just want the two boxes to disappear.
I would recommend the following: try to put rectangles (squares) under each box, and “attach” them to each other and to the edges of the screen. Make them white/transparent. Something like this:
And then put your existing boxes inside these rectangles. Of course, don’t forget to adjust the layout “priority” in Screen->Components, so that your boxes are “on top” of these rectangles.
Adalo layout tries to be responsive, sometimes it produces such effects
