How can I get a "Responsive" response form to open up in a modal popup window with a "OK" button?

In the web form builder click on settings then on the general tab select Display form in popup.
When you place the html on your page change the default Click me text for OK.

How do I make the popup work with a navbar link. That is, when someone clicks on a buttonized link in my main navbar like say 'contact,' a popup window opens with the form?

Thanks guys.

Probably the best thing to do is to use an html box and hand code a nav button image to be linked to your form. So create an image for your button. Now add this image to a folder of your choice. Adjust the code to match your folder and image name and type. Also adjust the code to your form name
