iterateInitialNavNodes

Use

Iterates through the top-level navigation nodes.

During each iteration of the tag, a different node is exposed in the body of the tag, either via a cooperating tag that accesses the current node in the iteration or the scriptlet variable defined by the currentNavNode attribute.

Attributes

Name	Mandatory	Description
`currentNavNode`	No	The name of the Java variable to create for holding the `INavigationNode` object for the current node in the iteration. The variable can be accessed in scriptlets in the body of the tag.
`direction`	No	Indicates in what direction to iterate. The attribute can have the following values: forward (default) : Iterate from the first to the last node. backward: Iterate from the last to the first node.

The variable can be accessed in scriptlets in the body of the tag.

direction

forward (default) : Iterate from the first to the last node.
backward: Iterate from the last to the first node.

Variables

Name	Scope	Description
< currentNavNode > attribute	Body of tag	`INavigationNode` object representing the current node in the iteration.

Example

The following iterates through all the top-level navigation nodes and creates a link for each one.

<ul>
<nav:iterateInitialNavNodes>
    <nav:ifNavNodeInSelectedPath>
        <li class="selectedLevel1">
            <nav:navNodeAnchor navigationMethod="byURL"/>
        </li>
        <% if(levels==2) { %>
            <nav:storeNavNode/>
        <% } %>
    </nav:ifNavNodeInSelectedPath>
    <nav:ifNotNavNodeInSelectedPath>
        <li class="unselectedLevel1">
            <nav:navNodeAnchor navigationMethod="byURL"/>
        </li>
    </nav:ifNotNavNodeInSelectedPath>
</nav:iterateInitialNavNodes>
</ul>
