Expand the Tree to a specific level

How can I use node.setExpanded(true);

to expand the tree only to a certain level?

What I mean is that I have 6 depth levels and only need 5 to be expanded - the last one should be excluded.

This is just a guide, since you didn't provide any sample data or code, but you can use a recursive function to iterate through the tree, stopping when a certain depth is reached. Something like:

function expandNode(node, depth) {
    // Expand this node
    // Reduce the depth count
    // If we need to go deeper
    if (depth > 0) {
        for (var i = 0; i < node.children.length; i++) {
            // Go recursive on child nodes
            expandNode(node.children[i], depth);


and call it root node and total depth:

expandNode(rootNode, 5);


There might be better techniques for iterating fancytree, but I haven't used fancytree before



        if(node.getLevel() < 3) {
