Why does the drop-down to drilldown in my dashboard not work with my current XML?

[smhsplunk]

I am trying to activate a drop-down such that when I choose any of the items,
a drilldown activates and goes to a new view. I cannot activate this drilldown.
Following is the code.

  <fieldSet submitButton="true" autoRun="false">
  <row>
    <panel>
       <input type="dropdown" token="state_token" searchWhenChanged="true">
      <label>State Names</label>
      <default>-</default>
        <populatingSearch fieldForValue="state_name" fieldForLabel="state_name">
          <![CDATA[index=location source=traffic_locations | fields state_name ]]>
        </populatingSearch>


         <drilldown>
            <![CDATA[
               /app/myapp/page6?form.state_name=$state_token$
             ]]>
         </drilldown>
                <option name="wrap">true</option>
        <option name="rowNumbers">false</option>
        <option name="dataOverlayMode">none</option>
       </input>
    </panel>
  </row>
</fieldSet>

There is no drilldown possible from the data input. YOu should use a visualization element to be able to drilldown
