List Values Opens a dialog box that lets you add the items to a form menu: 1 Use the Plus (+) and Minus (-) buttons to add and remove items in the list. 2 Enter label text and an optional value for each menu item. Each item in the list has a label (the text that appears in the list) and a value (the value that is sent to the processing application if the item is selected). If no value is specified, the label is sent to the processing application instead. 3 Use the up and down arrow buttons to rearrange items in the list. Items appear in the menu in the same order as they appear in the List Values dialog box. The first item on the list is the selected item when the page is loaded in a browser. Dynamic Lets the server dynamically select an item in the menu when it is first displayed. Class Lets you apply CSS rules to the object. Initially Selected Sets the items selected in the list by default. Click the item or items in the list. Hidden field object options HiddenField Specifies the name for the field. Value Assigns a value to the field. This value is passed to the server when the form is submitted. Class Applies CSS rules to the object. About dynamic form objects A dynamic form object is a form object whose initial state is determined by the server when the page is requested from the server, not by the form designer at design time. For example, when a user requests a PHP page that contains a form with a menu, a PHP script in the page automatically populates the menu with values stored in a database. The server then sends the completed page to the user's browser. Making form objects dynamic can simplify site maintenance. For example, many sites use menus to present users with a set of options. If the menu is dynamic, you can add, remove, or change menu items in a single place-the database table in which the items are stored-to update all instances of the same menu on the site. See also "Defining sources of dynamic content" on page 547 Insert or change a dynamic HTML form menu You can dynamically populate an HTML form menu or list menu with entries from a database. For most pages, you can use an HTML menu object. Note: For ASP.NET pages, you must use a DropDownList or ListBox form control. Before you begin, you must insert an HTML form in a ColdFusion, PHP, ASP, or JSP page, and you must define a recordset or other source of dynamic content for the menu. 1 Insert an HTML List/Menu form object in your page: a Click inside the HTML form on the page (Insert > Form > Form).
