Categories with JSON data

[andy8Participant]

Hello All,

Is it possible to set up categories (groups) in jqxDropDown List populating from JSON feed? I have seen the example using arrays and am not sure how to do the same for JSON data. I have tried this code:

    var events = {
        datatype: "json",
        type: 'POST',
        datafields: [{name: 'events'}, {name: 'id'}, {group: 'gr'}],
		id: 'id',
        url: '/test.php',
        data: {
            mode: "events"
        },
        async: false
    };
    var eventAdapt = new $.jqx.dataAdapter(events, {
        autoBind: true
    });
	$("#str_scen").jqxDropDownList({
        checkboxes: false,
        source: eventAdapt,
        displayMember: "events",
       .........

but it doesn’t work. I could convert JSON to array and feed the dropdown list directly, but it would be nice to designate categories in JSON.

Pls advise.

Thanks

Hi andy8,

It is still not possible to have categories when the widget is bound to JSON data.

Hi Peter,

Thanks for the reply. Is it possible to add groups after the dropdown list is rendered with the ‘updateItem’ directive?

I’ve tried modifying an existing dropdown list, but it makes no difference and doesn’t add categories.

Hi andy8,

“updateItem” does not group the list items by groups. I am sorry, but your scenario is still not supported by our widget..
