Hi there,
Is that for the button “Find my answer” or for “Add to my dashboard”? That’s because I click the “Add to my dashboard” and nothing happens. But yes, I think doable. Example, let’s use “Find my answer” button as a sample.
You’ll have to edit the form and add target=”_top” on <form> element. ( http://www.w3schools.com/tags/att_form_target.asp ). Since it’s ninja form, then it should offer a similar option and you should check their documentation.
And for the link, it can be like this (this is not applicable for cornerstone button so you have to manually add these classes x-btn x-btn-flat x-btn-rounded x-btn-large)
<a href="link here" target="_top" class="x-btn x-btn-flat x-btn-rounded x-btn-large">Add to my dashboard</a>
Hope this helps.
