To add or edit a picker (selector) on an offer, start by opening the bundle editor:
Go to the bundle editor, then open the Offers tab.
Expand the relevant offer by clicking the small arrow.
Enable Show picker.
Then choose a style under Selector Style:
Radio
Check mark
Square
Star
Switch
Important: if your picker disappears
If you enable Use product image on offer, MoonBundles may sometimes automatically hide the picker.
Simply re-enable Show picker and everything will work normally.
If the issue persists, contact MoonBundles support. They’ll be able to check your setup quickly.
