"Cascading combo boxes are used to help aid the user in determining a choice when entering data into a form.The user can select, for example, Customer Services in a combo box and the second combo box's list will reflect this selection and only list those employees within Customer Services.
They help to breakdown the options available into selectable sub-groups such a State & City, Product Type & Product, Department & Employees.
Switch to Finance and all the Finance employees become selectable, etc."
