Plus, as an added bonus — and this made my day when I installed it 😀 — you can change most of the rendered markup for forms in Views that ship with the module (these are installed into ~\Views\Form\EditorTemplates\ of your Sitecore instance).
However, the other day, I discovered the submit button text is hard-coded in one of the module’s Views:
As you may know, the module does provide a field on Form Items to change the submit button text:
Unfortunately, the value of this field is not being put into the value attribute of the submit button in the View above.
I have alerted Sitecore support of this issue via a ticket though do recommend modifying ~\Views\Form\EditorTemplates\FormModel.cshtml to use the submit button text set on the Form Item if you are using WFFM on Sitecore MVC:
As you can see, the value of the submit button text field is set on a property of the model, and can be easily be put into the value attribute of the submit button.
If you have any thoughts on this, please share in a comment.
