Avoid duplicate entries in structure field

Hello!

Is there a simple way to prevent duplicate entries in a structure field, so that an editor cannot make duplicate entries? Or at least the editor is notified if something like that happens?

You could check that with a hook, either before saving (page.update:before) or after (page.update:after).

ok, thanks.
Then i will look into it…

Best regards,
Robert
