Is it possible to use the “Insert/edit link” dialog box outside of TinyMCE? For example, if I wanted to add that dialog box to a generic button within a plugin settings form, is it possible to include just the portion of the TinyMCE that is required to make it work?
Utilize TinyMCE hyperlink chooser outside of TinyMCE
this was asked before, but sadly the “Insert/edit link” (with interlinking) was developed as a tinymce plugin so using it outside of tinymce is not really possible unless your write the whole thing from scratch.
