View Mode Selector
Security covered
A small module which allows you to change the view mode of an entity.
This module provides a new field type "View mode selector", so just go to "Manage fields" and create a field of that type and choose between a "select list" and a "radio buttons" widget. When you choose "radio buttons" it is possible to upload an icon which will be displayed instead of the view mode name.
In order to display your referenced entities with the new "View mode selector" view mode don't forget to change the view mode on "Manage display" which is used for displaying them.
If Display Suite is enabled, it can also display a live preview of the configured view mode layout. Here is an example:
