I want to show/hide a drop-down based on a value selected from another drop-down.
Anyone having Jscript for disappering a dropdown while selecting a value from another dropdown.

This can only be achieved using custom Javascript. You will have to create the HTML Dashboard or a specific javascript to include in the Simple XML view that checks the value of the first dropdown, and then adjust the second drop down based on that condition.
