What it is
Every popup is built for mobile from the start: the build makes a separate desktop and a mobile version of the same popup, and you can edit either one.
Because they are separate designs, you can tune the mobile version without touching desktop. Hide an element that takes too much room on a phone, and desktop keeps it.
In the editor, the monitor and phone icons switch between the two, and a size dropdown previews different screens.
Key benefits
The mobile version is drawn for a phone screen.
Change or hide what doesn't fit, without touching desktop.
After a text edit, the editor asks whether to apply it to the other view too.
How it works
The mobile version comes with every build.
In the editor, switch to the phone icon and try a few screen sizes.
Make your changes, answer the sync question, and save. You're warned if something overflows.
Step-by-step setup lives in the Help Center guide.
No. Every build makes a desktop and a mobile version.
After a text edit, the editor asks whether to apply it to the other view. A badge shows when the two differ, and you get a warning if an edit couldn't be carried over.
Yes. Select it in the mobile view and use Hide element.
