iterateSelectedNavNodesLevel

Iterates through all the sibling nodes of the node in the selected path on a specified level.

For example, if the user selects System Administration Permissions SAP Authorizations , and the tag specifies level 2, then the tag iterates through all the nodes on the same level as Permissions.

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.

For more information about the selected path, see Key Terms and Concepts.

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 is accessible 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
`level`	Yes	The level in the navigation tree whose nodes to include in the iteration. Only the children of the selected node on the level above are included.

Name

Description

currentNavNode

The name of the Java variable to create for holding the INavigationNode object for the current node in the iteration.

The variable is accessible in scriptlets in the body of the tag.

direction

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

level

Yes

The level in the navigation tree whose nodes to include in the iteration. Only the children of the selected node on the level above are included.

Variables

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

Example

The following creates a detailed navigation iView by starting an iteration of all the sibling nodes of the node in the selected path on the strStartLevel level.

Syntax Syntax

<div id="dtn">
    <nav:iterateSelectedNavNodesLevel level="<%=strStartLevel%>"
     currentNavNode="currentRoot">
        <nav:recurseNavNodeChildren currentDepth="currentDepth"
         currentNavNode="currentNavNode">

        ... Display DTN nodes

        </nav:recurseNavNodeChildren>
    </nav:iterateSelectedNavNodesLevel>
</div>
