apex:panelBar

A page area that includes one or more <apex:panelBarItem> tags that can expand when a user clicks the associated header. When an <apex:panelBarItem> is expanded, the header and the content of the item are displayed while the content of all other items are hidden. When another <apex:panelBarItem> is expanded, the content of the original item is hidden again. An <apex:panelBar> can include up to 1,000 <apex:panelBarItem> tags.

This component supports HTML pass-through attributes using the "html-" prefix. Pass-through attributes are attached to the generated container <div> tag.

Example

<!-- Page: panelBar --> 

<!-- Click on Item 1, Item 2, or Item 3 to display the content of the panel -->

<apex:page>

    <apex:panelBar>

        <apex:panelBarItem label="Item 1">data 1</apex:panelBarItem>

        <apex:panelBarItem label="Item 2">data 2</apex:panelBarItem>

        <apex:panelBarItem label="Item 3">data 3</apex:panelBarItem>

    </apex:panelBar>
