Hi Sandro, you haven’t shared your readonly designer link + details on where to find it, so I can’t see where this is happening. However the readonly view sometimes excludes settings anyway.
In my localized sites these setups work fine-
CMS collection X contains a Link field, populated with external URLs
Collection list bound to X contains a link, and can be bound to that field.
also…
Collections page for X contains a link, and can be bound to that field
If you’re doing something else like a nested list, you may have hit an edge case bug.
Main thing would be to contact support.
Workarounds;
If you can bind it to a custom attribute field, you could set it to x-href on your link element directly, and then use SA5’s dynamic attributes lib.
Failing that, you might be able to get that field content in an HTML embed, and then have a small script apply it to the href of the links you want.
