with single select no fields

Hi,

I want to change a multi select field to a checkbox (single) field.
When I change the fieldtype however, all selectable fields disappear and there is no possibility to add any field.
When I create a new single select field this is the same. All other filed types with selectable field values are functioning properly.



What to do about this?

Greetings,
Paul

Single checkbox doesn't have options. It's a simple Yes/No usage. You'd need to use a multi-checkbox if your want custom options.
