Expand tree node via javascript

mail.micke Nov 12, 2007 11:15 AM

Hi,
I would like to expand collapsed nodes when the text for the node is clicked, how can I do this?

Is there some java script functions that I can use?

Many thanks,
Mike

Sorry to bump this post, but I'm hoping to find out quite quickly if this is possible.

We plan to use the tree for navigation, and the current struts version of the application also uses a tree where the text for collapsed nodes is clicked to expand and really need this otherwise our users will get confused :)

Did you try with a nodeSelectListener?

 public static void expandNode(NodeSelectedEvent event) {
 HtmlTree tree = (HtmlTree) event.getComponent();
 Object selectedObject = tree.getRowData();
 // open node
 TreeRowKey rowKey = (TreeRowKey) tree.getRowKey();
 tree.queueNodeExpand(rowKey);
...
