Insert ColdFusion select boxes

You can visually insert a ColdFusion select box into your form and set its properties. A select box lets a visitor select one

or more items from a list. Select boxes are useful when you have a limited amount of space, but need to display many

items. They’re also useful when you want to control the values returned to the server. Unlike text fields, where users can

type anything they want, including invalid data, with select boxes, you can set the exact values returned by a menu.

You can insert two types of select boxes into a form: a menu that “drops down” when the user clicks it, or a menu that

displays a scrollable list of items that the user can select.

Note: This enhancement is available only if you have access to a computer running ColdFusion MX 7 or later.

2 In the CFForm category of the Insert panel, click the CF Select icon.

A select box appears in the ColdFusion form.
