How to reveal a second panel based on user input?

[splunkrocks2014]

Hi. I have a dashboard with a textbox that allows users to search a specific host or IP which is set to "" by default. Due to the limitation from max result from a subsearch, I am unable to get all the results from the default value. I want to create two different panels (panel A and B) with different search queries: When the users input "" only from the textbox, it shows "panel A", and "panel B" is hidden; otherwise, it shows "panel B" and hides "panel A". Does anyone have any suggest how to handle this? Thanks.

Basically, you are looking for depends and rejects on your panel.

Choose your token, then use set/unset to determine whether the panel will appear.
