In my Drupal 7 website I have an A content type with an entity reference 'parent' field which I use to link to nodes of a B content type.
I have to implement a way to sort A nodes basing on their B parent.
Modules such as Nodeorder and Nodequeue (smartnodequeue) can achieve this with term references. Is there any way to sort them based on entity references without creating vocabularies and term reference fields? I would prefer a draggable solution.
