Filterable Link

TL;DR Use Link Field Autocomplete Filter

Wouldn't it be nice if you can specify which bundles an instance of the core link field can source? This module attempts to streamline the linking of internal content by defining what bundles a custom instance of the core link field can reference.

This module could be useful if your site has similarly named content, but they are crafted from different bundles, or if your bundle type has a specific linking purpose.

Each instance of the field type allows an admin to specify target bundle types that ultimately filters the field's autocomplete responses.
