I don’t see how to add the tags to an object in the demo? I want to do something similar to Facebook and LinkedIn where users can enter a strong of tags separated by hashtags. As the user types, the platform suggests tags but if the user doesn’t select one of the suggestions the “new to the system” tag is added to the database. See screenshot.
Thanks for reaching out!
If you are talking about the Flat and Modern Tags plugin then you can add tags simply dragging-and-dropping the Tag element on the page in the Editor.
But, unfortunately, using this plugin won’t be possible to achieve your described purpose. It simply adds the tags on the page that redirect on the appropriate page.
Hope this helps!
