How can I manually filter the dataSource instance of the MultiSelect?


The Kendo UI MultiSelect has a built-in detection mechanism that checks whether the data is filtered or not. The widget uses this information to decide when to persist the selected value that does not exist in the source. When the source is manually filtered, the widget loses the details about the state of the DataSource, which might lead to inconsistent behavior.

The following example demonstrates how to achieve the desired scenario.

<div id="example">
    <div class="demo-section k-header">
        <select id="multiselect" multiple="multiple"></select>
        $(function() {
            var ms = $("#multiselect").kendoMultiSelect({
                dataTextField: "name",
                dataValueField: "value",
                dataSource: {
                    data: [{ name: "One", value: 1 }, { name: "Two", value: 2 }]

            //Filter the source manually
                field: 'value',
                operator: 'eq',
                value: 1

            <!-- IMPORTANT: Update filter state of the widget -->
