Height (List type only) Sets the number of items displayed in the menu.

Selections (List type only) Indicates whether the user can select multiple items from the list.

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.

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.
