dataSource Object|Array|kendo.data.DataSource

The data source of the widget which is used to display a list of values. Can be a JavaScript object which represents a valid data source configuration, a JavaScript array or an existing kendo.data.DataSource instance.

If the dataSource option is set to a JavaScript object or array the widget will initialize a new kendo.data.DataSource instance using that value as data source configuration.

If the dataSource option is an existing kendo.data.DataSource instance the widget will use that instance and will not initialize a new one.

Example - set dataSource as a JavaScript object

<select id="multiselect" multiple="multiple"></select>
<script>
$("#multiselect").kendoMultiSelect({
  dataSource: {
    data: ["One", "Two"]
  }
});
</script>

Example - set dataSource as a JavaScript array

<select id="multiselect" multiple="multiple"></select>
<script>
var data = ["One", "Two"];
$("#multiselect").kendoMultiSelect({
  dataSource: data
});
</script>

Example - set dataSource as an existing kendo.data.DataSource instance

<select id="multiselect" multiple="multiple"></select>
<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    read: {
      url: "https://demos.telerik.com/kendo-ui/service/products",
      dataType: "jsonp"
    }
  }
});
$("#multiselect").kendoMultiSelect({
  dataSource: dataSource,
  dataTextField: "ProductName",
  dataValueField: "ProductID"
});
</script>
