Using custom UI controls in extensions 113

In most cases, DOCTYPE statements must go on the first line of a document. However, to avoid

conflicts with extension-specific directives that, in previous versions, were required to be on

the first line of a file (such as the comment at the top of a Property inspector file, or the

MENU-

LOCATION=NONE

directive in a command), DOCTYPE statements and directives can now be in

any order as long as they appear before the opening

html tag.

In addition to letting you make extension UIs more closely match the built-in dialog boxes

and panels, the new

DOCTYPE statements also let you view your extensions in the

Dreamweaver Design view so that you can see them as they would appear when viewed by

users.

The following examples show the Base Property inspector without the

DOCTYPE statement,

which improves form-control rendering, and then with the

DOCTYPE statement.

Using custom UI controls in extensions

In addition to the standard HTML form elements, Dreamweaver supports custom controls to

help you create flexible, professional-looking interfaces, as described in the following list:

■ Editable select lists (also known as combo boxes) that let you combine the functionality of

a select list with that of a text box

■ Database controls that facilitate the display of data hierarchies and fields

■ Tree controls that organize information into expandable and collapsible nodes

■ Color button controls that let you add color picker interfaces to your extensions
