I've just started learning Drupal 7 and while I was creating a blog I wanted to give it a relation but it must be related to multiple articles through taxonomy terms.
In the Blog content type, I created a relation field, set the Field Type to Term Reference and Widget to Check boxes/radio buttons.
Here is a snapshot http://varunsharmak2.com/blog-content-type.png
Now when I create a blog entry, it shows all the Taxonomy terms as radio buttons in Relation section.
Here is a snapshot of it. http://varunsharmak2.com/relation.png
I want checkboxes in place of radio buttons.
How can I get check boxes?
