How to add left list in Enquiry window and populate data in it?

Hello All, 

For one of my project. I want to add the left list in my Enquiry window. 

I already attached object to browser tab of window but it only shows the empty left list. 

My main problem is to populate the data in this left list. I also tried to catch the action "GAUCHE" and "FILGAUCHE" but none of the action is getting executed. 

Any suggestion and help will really appreciated. 

Thank you..
