Webform Add More enables selected fieldsets to be initially hidden and progressively shown with an Add more button, mimicking CCK multiple fields. The approach was proposed by Bartezz, and code originally implemented by span and kranklin . This module adds a checkbox setting to webform fieldset components to select which should have Add more functionality, as well as an advanced setting to override the button label per Webform.
jQuery Livequery plugin (included).
After enabling the module, configure two or more webform fieldsets to use Add More. To change the Add more button label, edit the Form settings Advanced settings.
