Hello Stephan,

Here is how to add a custom class to some items when the tree is loaded from an HTML structure:

<!DOCTYPE html>
<html lang="en">
<head>
    <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" />
    <style type="text/css">
        .customItemClass
        {
            background-color: Green;
        }
    </style>
    <script type="text/javascript" src="../../scripts/jquery-1.10.2.min.js"></script>

    <script type="text/javascript" src="../../jqwidgets/jqxpanel.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxtree.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxcheckbox.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            // create jqxTree
            $('#jqxTree').jqxTree({ height: '400px', hasThreeStates: true, checkboxes: true, width: '330px' });
            $('#jqxTree').css('visibility', 'visible');
            $('#jqxCheckBox').jqxCheckBox({ width: '200px', height: '25px', checked: true });
            $('#jqxCheckBox').on('change', function (event) {
                var checked = event.args.checked;
                $('#jqxTree').jqxTree({ hasThreeStates: checked });
            });
            $("#jqxTree").jqxTree('selectItem', $("#home")[0]);
        });
    </script>

Hi Dimitar,

thanks a lot. Is there any chance to add custom classes when loading the content from json?

Hi Stephan,

Unfortunately, this is not supported, but you can add a custom class to some items after you have gotten them with getItems:

<!DOCTYPE html>
<html lang="en">
<head>
    <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" />
    <style type="text/css">
        .customClass
        {
            color: Red;
        }
    </style>
