/settings/admin/additional has the option to add external links into the OC user menu. I need to add a link to an external application where the UI is not embeddable under the main OC UI. Instead it should be opened as a separate tab (target=” _blank). How can this be achieved?
The External app was not made for that, its goal is having the external site within ownCloud. But wasn’t the Bookmark app made exactly for that?
Of course, you wont have shown your external site in an extra menu item, unfortunately.
If the extra menu menu item is a fixed requirement, I only see to extend the External app with such feature or create an own app for that purpose.
Or maybe this could help: I would try to create HTML-file somewhere on the server and configure the external app to point there. Finally this HTML-file could open your site in a new tab.
