one Dropdown output as input to another dropdown
HI,
In first drop down I need to display locations as location 1, location 2 etc. If i select Location 1, the second drop down should list the meters of the Location 1. for ex. meter 1, meter 2 etc. If I select meter 1 the current and power values should be displayed in a LED widget.
Similarly for Location 2. How to do this?
