I have a content type which shows a list of other nodes connected via an entity reference field.
These nodes are loaded through an entity field query in a preprocess_node module, then displayed using node_view_multiple.
What I would like to do is add a checkbox to each node with a submit button at the bottom.
Essentially this is to setup a way to delete nodes from the content page, without having to go into the admin menus. I'm a bit confused where to start with adding the form elements in this setup.
