The issue remains at two levels:
- The destination URL appears on the button even without specifying any URL, but the link is not active (which makes sense, given that no parameter was set in the href attribute, resulting in no active link).
- Since each button has a different URL, how should this be handled with the solution you provided?
For your information, the "Read More" link and "Read More with Title" options in the menu item are set to "Hide".
