Here is an example of a lightbox.
The Web Forms application includes a robust Boxes Editor for you to create lightboxes with.
Lightboxes and other widget types are shown to your website visitors according to the conditions that you create. Conditions determine the circumstances under which a lightbox is displayed. A lightbox must have at least one condition set in order for it to be eligible for display. Multiple conditions can be grouped into Rulesets which can then be reused with other lightboxes. Because lightbox conditions can become complex, Master Rules are available to help ensure that lightboxes are displayed as you expect them to.
You create conditions within the Web Form's interface by using the Edit link in the Conditions column.
You can test your lightboxes before publishing them to your production website. Read more about testing lightboxes in QA Mode.
You can run AB and Multivariate Tests within Web Forms. These tests allow you to determine which variation of a lightbox is the most effective.
