    Is it possible to use a grouped Datasource in the DropDownList? I just want to use the groups for something like optgroups in html selects.

    Thanks in advance.

    Has there been an answer on this anywhere?

    For example, I would like to have a DropDownList use the "ipPart3" field from the following datasource for both the text and value in options:

    var ipPart3 = new kendo.data.DataSource({
        data: [{"ip_part_1":"192","ip_part_2":"168","ip_part_3":"123","ip_part_4":"134/32"},
    {"ip_part_1":"192","ip_part_2":"168","ip_part_3":"123","ip_part_4":"142/32"},
    {"ip_part_1":"192","ip_part_2":"168","ip_part_3":"123","ip_part_4":"131/32"},
    {"ip_part_1":"77","ip_part_2":"234","ip_part_3":"42","ip_part_4":"58/32"},
    {"ip_part_1":"192","ip_part_2":"168","ip_part_3":"123","ip_part_4":"129/32"},
    {"ip_part_1":"192","ip_part_2":"168","ip_part_3":"123","ip_part_4":"150/32"},
    {"ip_part_1":"192","ip_part_2":"168","ip_part_3":"123","ip_part_4":"149/32"},
    {"ip_part_1":"192","ip_part_2":"168","ip_part_3":"123","ip_part_4":"50/32"},
    {"ip_part_1":"10","ip_part_2":"200","ip_part_3":"211","ip_part_4":"10/32"}],
        schema: {
            model: {
                fields: {
                    ipPart1: {type: "string"},
                    ipPart2: {type: "string"},
                    ipPart3: {type: "string"}
                }
            }
        },
        group: [{field: "ipPart1"}, {field: "ipPart2"}, {field: "ipPart3"}]
    });



    .. but, I can't determine the way to specify the dataTextField & dataValueField options to get this to work.

    Hello Josh,

    Currently, Kendo UI DropDownList does not support binding to grouped data source. I would suggest you cast your vote for this functionality in the opened UserVoice discussion. We adjusts our road-map based on the top voted items.
