Adding a radio button to a Drupal View page Does anyone know how to 'inject' a radio button onto a Drupal View page? 

I have an exposed filter that has nothing to do with a radio button but I want to add a radio button in front of the label in order to apply some additional AJAX to it.
Use HTML &lt;form&gt;, ex: w3schools.com/html/tryit.asp?filename=tryhtml_form_radio

To "inject" your code you could add a header text field to your view OR create a template file for your view.
