Hello,
The functionality should not depend on whether the item is a link, page, or category. Upon clicking, the settings menu should open in the response area on the right. If this is not happening on your site, we kindly request the opportunity to check the settings for you.
To proceed, we would need temporary wp-admin access to your website. Please let us know if you can provide this so we can assist you further.
To grant WP-Admin access, please proceed to create a new user account with an administrator role through your WordPress Dashboard. Once the account is established, you may securely transmit the username and password to us via the Private Content section designated for this purpose.
Best regards,
8Theme Team
