When you define your fields datatype and filter as select. Magento will automatically display your column filter as dropdown.

    <column name="type">
        <argument name="data" xsi:type="array">
            <item name="options" xsi:type="object">Namespace\Modulename\Model\Config\Source\Departments</item>
            <item name="config" xsi:type="array">
                <item name="filter" xsi:type="string">select</item>
                <item name="component" xsi:type="string">Magento_Ui/js/grid/columns/select</item>
                <item name="dataType" xsi:type="string">select</item>
                <item name="sorting" xsi:type="string">asc</item>
                <item name="sortOrder" xsi:type="number">2</item>
                <item name="label" translate="true" xsi:type="string">Departments</item>
