The AllWebMenus Web Modal Windows Addin is free and included in AllWebMenus Build #792 or above by default.
It is actually used to enable an easy, direct call of a jQuery modal window from any menu item through the interface (<Open Modal Window> property).
However, the javascript modal window should be created by a licensed installation of the separate product that actually builds the modal window: the "Likno Web Modal Windows Builder".
