Accordion component (Flash Professional only)

The Accordion component is a navigator that contains a sequence of children that it displays one
at a time. The children must be objects that inherit from the UIObject class (which includes all
components and screens built with version 2 of the Macromedia Component Architecture); most
often, children are a subclass of the View class. This includes movie clips assigned to the class
mx.core.View. To maintain tabbing order in an accordion's children, the children must also be
instances of the View class.
An accordion creates and manages header buttons that a user can click to navigate between the
accordion's children. An accordion has a vertical layout with header buttons that span the width
of the component. One header is associated with each child, and each header belongs to the
accordion—not to the child. When a user clicks a header, the associated child is displayed below
that header. The transition to the new child uses a transition animation.
An accordion with children accepts focus, and changes the appearance of its headers to display
focus. When a user tabs into an accordion, the selected header displays the focus indicator. An
accordion with no children does not accept focus. Clicking components that can take focus
within the selected child gives them focus. When an Accordion instance has focus, you can use
the following keys to control it:
