Hi
@KPrasanth9
I tried this myself and got it working. I am attaching the screenshots for your help.
Simply spy the element(Show entries drop down) using the html mode and then use 3 navigate stages.
The 1st one for launch.
2nd one for selecting the Show entries drop down &
3rd one for using global send keys and type "{DOWN 3}" for pressing the down key 3 times,
That will fix the issue.
