    Hi there,

    I want to change the text on the fly.

    I have a menu:

    
    <div id='jqxMenu' style="background-color:white">
                <ul>
                    <li>nr1</li>
                    <li id="somethingnew">Nr2
                    <li>Nr3</li>
                </ul>
    </div>
    

    Javascript:

    // e.g. Clicking in a grid:
    $(“#jqxgrid”).on(“cellclick”, function (event)
    {
    $(“#somethingnew”).html(“newtext”);
    contextMenu.jqxMenu(‘open’);
    }

    var contextMenu = $(“#jqxMenu”).jqxMenu({
    width: ‘260px’,
    autoOpenPopup: false,
    mode: ‘popup’,
    rtl: true
    });

    But the “newtext” won’t appear.

    Any idea?

    Regards
    Chris

    Hello Chris,

    We experience no such issue (with the latest version, 3.4.0). Here is an example, based on the demo Context Menu:
