I have created 2 Content entities. Entity A has an "Entity Reference Field" with multiple values to Entity B. This all work as expected.
What I want to achieve is, to create a link from Entity B page, that when the user clicks on it, it will be added (appended) to Entity A "Entity Reference Field".
What's the best way to get this done?
- (I know I can use the Flag and Flag lists module, but there are limitations to it like it will be impossible/difficult to make these lists public/anonymous. After trying Flag lists out, it also didn't feel like a very Drupal native approach.)
- (Getting a list of referenced items etc. is an other challenge, but my biggest problem is to get the linking approach working first.)
