I work with limited content using a membership plugin. Everything works great. The only problem is that if I give the user the option to create a post using the frontier, he can see the names of all pages and posts on the site and link to them using the link.

If he inserts a link in the editor, he can display a pop-up window to insert / edit the link and in this window he sees a list of all pages and posts of the site.
Look at the picture. I highlighted in red what I wanted to hide.

Although it cannot display their contents, the display of the list and names is also inadmissible.

That is unacceptable to me.

Thx

Can you think of a way to hide these links? Ideally, the user would only see links to their own pages and posts they created. Thanks for the help.
