A field for Advanced Custom Fields which allows users to select a list of created custom fields

ACF control for field creation
The filed selector field allows the selection of other custom fields. This is useful in situations where you want to give the user powerful display options. You could, for example, allow the user to select which custom fields are displayed in a post.
This ACF field type is compatible with both ACF 4 and ACF 5.
