 h2. Overview
 _Since 3.0_
 Panel is a generic grouping component that supports toggling, closing and an options menu.
 {tip}See the ICEfaces Showcase [Live Demo|] of this component, complete with source code.{tip}
 h2. Getting Started
 {code:xml|borderStyle=dashed} <ace:panel header="ICEfaces Header"
  <f:facet name="options">
 h2. Attributes
 {tip:title=TagLib Documentation}This section covers attributes involved in the typical use-cases for this component. For reference, the complete taglib documentation for this component is available [here|].{tip}
 *closable* specifies whether the panel has a button to hide the panel by using the jQuery fadeOut() function.
 *toggleable* specifies whether the panel has a button to collapse/expand the contents of the panel by using the jQuery slideToggle() function.
 *collapsed* specifies whether the panel is collapsed.
 *footer* specifies the footer text of the panel.
 *header* specifies the header text of the panel.
 h2. Event Listeners
 h2. Client Behavior Events
 | toggle | Fired when the toggle button is activated to expand or collapse the panel (default event). |
 | close | Fired when the close button is activated to remove the panel from view. |
 h2. JavaScript API
 The client side panel object is exposed through the global variable named by the *widgetVar* attribute, but currently there is no API useful to the user.
  h4. ICEfaces 3.x
 The client side component object is exposed through the global variable name specified in the *widgetVar* attribute.
 h4. ICEfaces 4+
 The "widgetVar" attribute on the ACE components has been removed in ICEfaces 4 and in its place a new "ice.ace.instance()" client JavaScript object lookup API has been introduced. The reason for this change is to enable lazy-initialization of the ACE component JavaScript objects to improve runtime performance and reduce browser memory use.
 {code}var widget = ice.ace.instance('frm:componentId);{code}
 {tip}The _ice.ace.instance_ function requires the _full_ client id of the component to be specified, such as "j_idt77:componentId" instead of just "componentId". To reduce the complexity of working with complete IDs with this function it may be preferable in some cases to use {{prependId="false"}} in the enclosing form (e.g. _<h:form prependId="false">_).{tip}
 {info}This component doesn't have a client-side API made specifically to be used by application developers. However, the component's internal methods and variables can be accessed in this way, including the underlying jQuery object and objects from underlying Javascript libraries (if applicable), and can be used for whatever purpose a developer might have in mind.
 h2. Keyboard and ARIA Support
 The following ARIA roles are supported: menu (for the menu button).
