with the built-in UI for OH3 there is the overview page which I completely designed for an ipad which includes multiple columns.
This overview page doesn’t look nice on an iPhone as there are too many columns.
Is it possible like you can do with Habpanel that you can have a different UI per device ?
I know I can create separate pages that fit on the iphone but the side menus cannot be seperated and I can not,have multiple overview pages.
The width is the default, so if you plan for phones (and you should) that would be the maximum size allowed for your column (often 100%), and then you select how much you want them to decrease when the screens get larger.
