Are you searching how to create drilldowns with hidden panels, which will pop only when you click on Drilldowns. Then you are in right place!!

 
So what is drilldown, Drilldown is a tool for configuring responses to user clicks on visualizations in a dashboard or form. Drilldown behavior is configured within individual visualizations. 
As pre-requisite, you will need a dashboard with two or more panels inside it.
 
Like here I have two panels which is Test Panel 1 & Test Panel 2,out of which I am going to hide the Test Panel 2 initially. And only get displayed when we click on the pie-chart inside the Test Panel 1.

 So we are going to add Drilldown for panel 1,

 

Click on Edit > More Actions
 

   Click on Edit Drilldown

Select on Click action in Drilldown Editor
 
 
Give some Name to Token Name and select $click.value$ for Token Value

Click on Apply, this will create Drilldown.
Now for that drilldown to be worked we have to edit source code of our dashboard.
 
Open Dashboard Source code
 
Make Following Changes To Hide Test Panel 2, by drilldown 

Add true  Tag inside drilldown tag of Test Panel 1 
 
Add depends=”$show_panel$“ inside panel tag of Test Panel 2, then click save.
Test Panel 2 is now hidden initially

Now if you click on any section of the pie charts, Test Panel 2 will get displayed.

Hence you have successfully created Drilldowns with Hidden Panels.
