Hiding Panels After Unhiding a New Panel

[strehb18]

Hello, 

In the past, I have used the checkbox method to hide panels after opening new ones. In this example, I would like to have a panel disappear after I click on the values in the panel. Currently, my next panel appears on the click, but the existing panel still exists. I'm wondering if there is any way to hide the panel that exists after i click on what I want to pass as the token. XML preferred.

You can use the drilldown from the second panel to unset the token used to show the panel.

My current efforts of <unset/> and <unset></> have not worked. Do you have an example of how to structure the token setup in the drilldown?

    <panel id="panel" depends="$showpanel$">
      <table>
        <search>...</search>
        <option name="drilldown">row</option>
        <option name="refresh.display">progressbar</option>
        <drilldown>
          <unset token="showpanel"></unset>
        </drilldown>
      </table>
    </panel>
