Order nodes based on entity reference filter 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.
Create a view that shows Content of type "A", add a relationship for Entity Reference: "B".  Then add a sort criteria and sort by Content "A".  Choose the relationship on the sort criteria as the relationship you made earlier.  You can expose the sort order so it can be chosen to sort ascending or descending.  This is not a draggable solution but it does allow you to sort by the referenced entity.
