Using tree components
The ICEfaces component library provides a robust tree component that can be used to render hierarchical data. By default, the<ice:tree> tag renders a tree component without any node icons, however, custom node icons can also be defined.
Using the default tree node icons
In this example, we bind the ICEfaces tree component to a model property in our backing bean that represents a set of files and folders on the file system.
<ice:form>
<ice:tree value="#{backingBean.treeModel}" var="item" hideRootNode="#{false}" hideNavigation="#{false}">
<ice:treeNode>
<f:facet name="content">
<ice:panelGroup style="display: inline">
<ice:outputText value="#{item.userObject.text}" />
</ice:panelGroup>
</f:facet>
</ice:treeNode>
</ice:tree>
</ice:form>
