The menu system of Vermont Views allows you to construct a series of menus that are linked together. Each menu contains an arbitrary number of menu fields that are displayed in a window. Each menu field is associated with an action function. When the user selects the field, the action function is called. The action function can call up a sub-menu or a sub-form that is associated with the menu field. Choosing a field in the sub-menu can invoke the display of still other lower levels of sub-menus. You can write your own action functions to do anything you desire.
