wp.selectionModel

The NavigationSelectionModel provides access to a selection model for a navigation model. The selection model is the navigation model from the perspective of the currently selected page, from which you can get to the selected page's ancestors and descendents.

Attributes:

  • children(node)

    Returns an iterator of child nodes.

    Example:

    <c:forEach var="node" items="${wp.selectionModel.children[wp.identification[wp.selectionModel.selected]]}">
        ${node}<br>
    </c:forEach>
    

    Parameters:

    • node

      Identifiable, or NavigationNode object to look up the children; it must not be null.

    Returns: An iterator with NavigationNode objects; it is never null.

  • hasChildren

    Determines whether the specified NavigationNode has associated nodes.

    Example:

    ${wp.selectionModel.hasChildren[wp.selectionModel.selected]}
    

    Parameters:

    • node

      Identifiable, or NavigationNode object to look up the children; it must not be null.

    Returns: Boolean; true if the node has children. Otherwise, it is false.

  • parent

    Access to the parent of a NavigationNode.

    Example:

    ${wp.selectionModel.parent[wp.selectionModel.selected]}
    

    Parameters:

    • node

      Identifiable or NavigationNode object to look up the children; it must not be null.

    Returns: LayoutNode; the parent node for the node if there is a parent. Otherwise, it is null.

  • path(node)

    Provides access to the path information for the node. The path represents the hierarchy from the root to the give node as a list. It is like a breadcrumb.

    Example:

    <c:forEach var="node" items="${wp.selectionModel.path[wp.selectionModel.selected]}">
        &lt;- ${node}
    </c:forEach>
    

    Parameters:

    Returns: a list of LayoutNodes representing the path from the root to the node.
