Buttons on entry forms have several capabilities. Learning to extend them can help you build even more power into your workflows. Button Types You'll notice that Rock ships with several different button types. These provide the basic styles for the buttons. You can define new types under Admin Tools > General Settings > Defined Types > Button HTML. When you define a button, you must provide mark-up for both a normal webpage and an HTML email. Cancel Buttons All buttons on a form will cause 'validation' to occur. This is a fancy term for checking that all the required fields are provided for. Sometimes though you want to provide a cancel button. Having to fill out all of the required fields just to cancel can be annoying. To keep the validation from occurring simply use the Cancel button type or change the {{ ButtonClick }} merge field to be "return true;".
