Prasanna, as a quick fix, I decided to set the menu item's command to the function that I wanted to be called when the user changes selections with the OptionMenu, and then put the line to set the dropdown's text in that function that is called. E.g.

def optionMenuChanged(event):
optionMenuWidget.setvar(unitNo_dropdown.cget("textvariable"), value = event)
#code to do what I originally wanted to do when the OptionMenu was changed
.
.
.
optionMenuWidget['menu'].add_command(label=myLabel, command=lambda temp=myLabel: unitNameChange(temp))

(I hope that code shows up legibly in the comments section!) Anyway, not the most elegant solution in the world, but it does what it needs to. Still, perhaps you can think of a better way. I also found Python MegaWidgets in my search for a solution, and though I haven't tried them out yet, it looks like the Pmw.ComboBox() might be a nice way to do it.

Great post. This is exactly what I'm looking for, except for one thing -- as far as I can tell, when you make the OptionMenu choices 'on the fly' the way you did, you lose the ability to set the OptionMenu's command. It is used up by the lambda function that changes the text of the OptionMenu. I wanted to also have a different function called whenever the user selected something with the OptionMenu, but I can't figure out how to do so. Any ideas?
