I can't find any field similar to WordPress native link popup (the same you find in WYSIWYG editor buttons – even in this support topic).
I'm looking for a field similar to ACF Link Field.
The Link field allows a link to be selected or defined (url, title, target) by using the native WordPress link popup.
It should optionally return an array of Link data (url, title, target) or the Link URL (string).
It's very useful to create relations with internal resources (posts, terms or other contents, also thanks to the powerful Better Internal Link Search, which includes taxonomies within search results).
To achieve the same you currently need to create a complex group of fields, with a Select field to choose between Post or Taxonomy or URL (external link) field + a Text field for custom link title + a Checkbox field for custom link target.
Is Link field already in your road map?
Thanks,
Davide
