Hello!
I have craeted a simple drop down menu with the help of data validation in cell "B3". The list contains 4 options, A,B,C and D. (Please see the attachment)

Now, as we all know, If I want to see this 4 option or select any one of them, I must first select the cell "B3". Then a down arrow will appear on right side of the cell. Selection.png

Only after Clicking this arrow, we can see the list. Clicking.png

My Requirement:
Just after selecting the cell "B3", the drop down list should appear automatically, without clicking the down arrow shown in right side of the cell.

Is there any way, any Macro, anything else to do that??

I do not want to use User Form. It may make the things more complicated, while I want to make the things more easy!

Thanks in Advance!!
