The code below has the drilldown setup to display panel4 when i click on panel3, and will only hide panel4 if i click on a link from panel4. How do I change it so that when i click on panel3 it will either show or hide panel4 depending on the state of panel4. For example if i click on panel3 and panel 4 is currently displaying, it will hide. If i click on panel3 again, it should now display the hidden panel4.
<row>
<panel>
<title>Panel 3 </title>
<single>
<search>
<query>|gentimes start=-1 | eval temp="Panel 3" | table temp</query>
<earliest>0</earliest>
<latest></latest>
<sampleRatio>1</sampleRatio>
</search>
<option name="drilldown">all</option>
<drilldown>
<condition match="boolPanel4 = true">
<set token="boolPanel4">true</set>
</condition>
<condition>
<unset token="boolPanel4"></unset>
</condition>
</drilldown>
</single>
</panel>
<panel rejects="$boolPanel4$">
<title>Panel 4</title>
<single>
<search>
<query>|gentimes start=-1 | eval temp="Panel 4" | table temp</query>
<earliest>0</earliest>
<latest></latest>
<sampleRatio>1</sampleRatio>

<option name="drilldown">all</option>
<drilldown>
<set token="boolPanel4">true</set>
