Webform Server draws all forms using standard HTML widgets when drawing check boxes, radio buttons, popups, and comboboxes. This may produce a slightly different look when compared to forms displayed in the Viewer. However, this does not change the functionality of the form. We recommend that you test your form in the Viewer and with Webform Server (on all platforms that the form will be viewed on).
