Hi Sri,
I suppose you can arrange a loop and execute the same test with varying parameters in each loop iteration. This will require transfering the application to the same initial state (that is, returning to the dropdown selection step) in the beginning of each loop, before selecting the values. If you need to use dropdown values, not an external file, as a data source, you can 1) get to the step when the dropdown appears 2) read all values from the dropdown to an array 3) enumerate the array's elements and handle each selection as a separate iteration - this will be the loop mentioned above.
