Re: HTML Menu/DBNested - Only want to display tree with 2 levels

Hi, Mark Reynolds wrote:

I have an array which I'm trying to display as a 'Tree' menu via 'HTML Menu' (example of the actual tree menu below, the array is below that). I've come across a few problems. Firstly, as you would expect when the 'tree' menu is displayed it displays three levels. Because I'm using the DirectTreeRenderer the menu is displayed in a list and I'm trying to find a way of just displaying 2 levels. Is this something I can limit as part of HTML menu or is it something I have to put in place when creating the actual array and if so, how do I do it? I've looked at

You can use something like this on $structure array you get from NestedSet before passing it to HTML_Menu:

    function trimTree(&$tree, $level)
    {
        foreach (array_keys($tree) as $key) {
            if (!empty($tree[$key]['sub'])) {
                if (1 == $level) {
                    unset($tree[$key]['sub']);
                } else {
                    $this->trimTree($tree[$key]['sub'], $level - 1);
                }
            }
        }
    }
