I have a multi select that is configured like this:

var config = {
    dataTextField: "Name",
    dataValueField: "Id",
    dataSource: new kendo.data.DataSource({
        transport: {
            read: {
                url: "/api/terms"
            }
        },
        filter: { field: "Name", operator: "neq", value: "Default" }
    })
};

For some reason the filter is not applied and "Default" is always shown as an option in the multi-select. Everything binds correctly otherwise. Am I missing something?

Hello Brian,

The MultiSelect widget persists all filters, which have different field value from the dataTextField option. Default filters, which filtrate the data on the same field as the dataTextField is not supported, because the widget creates and remove filters for the same field dynamically.
If you need to remove data then I would suggest you wire the change event and remove all unnecessary data items:
dataSource: new kendo.data.DataSource({
        transport: {
            read: {
                url: "/api/terms"
            }
        },
        change: function(e) {
             if (e.action !== "remove") {
                  var data = this.data();
 
                  //remove data
                  this.remove(data[0]);
             }
        }
    })
