Hide Sections Clicking Dynatree Value

Question

Have a tree structure like the following

Section 1
item1
item2
Section 2
item5

I can click on any item and hide all the other items with the dynatree onActivate function and this code

  onActivate: function(node) {
            var resultId = "#" + node.data.title;
            resultId = resultId.replace(/\s/g, '');
            $('#contents>div').not(resultId).hide();
            $(resultId).show();
        },

My html is this

<div class="container-fluid text-left">
    <div class="row content">
        <div class="col-sm-2 sidenav" id="tree"> </div>
        <div class="col-sm-8" id="contents">

            <div id="item1">
                <table id="item1grid"></table>
            </div>
            <div id="item2">
                <table id="item2grid"></table>
            </div>
            <div id="item5">
                <table id="item5grid"></table>
            </div>
        </div>
        <div id="info"> </div>
    </div>
</div>
</div>

How can I extend this html and function so if I click "Section 1" in the tree it shows all the items in that section only i.e. clicking "Section 1" only shows item1 and item2

Maybe you can achieve this by using some properties of incoming node object of 'onActivate' callback. You need to check that activated object is a folder and if so, display all the chidlren of this element. Try to append this snippet inside of your onActivate callback:

if (node.data.isFolder) {
    for (var i = 0; i < node.childList.length; i++) {
        $('#' + node.childList[i].data.key).show();
    }
}

Feel free to dump the entire object with console.log and check which fields you're able to use.

Could you please provide a jsfiddle to check what you're having so far?
