Best Practices for <apex:panelbar>

Adding a Collection of Child <apex:panelBarItem> Components to an <apex:panelBar> Component

An <apex:panelBar> component can only have <apex:panelBarItem> child components. Sometimes, though, you want to add a collection of child components. For example, you may want to add an item for each contact associated with an account. You can do this by wrapping <apex:panelBarItem> in an <apex:repeat> component, as follows:

1<apex:page standardController="account">
2  <apex:panelBar >
3    <apex:repeat value="{!account.contacts}" var="c">
4      <apex:panelBarItem label="{!c.firstname}">one</apex:panelBarItem>
5    </apex:repeat>
6  </apex:panelBar>
7</apex:page>
