Can I enter a dropdown list in one click? (Libre office calc)

Hi guys

Once I have created a dropdown list with data validity I want to be able to click on the cell once and see the dropdown rather than having to click once inside the cell and then click again to the right of the cell on the arrow that appears.
Is this possible?
At the very least can i add a permanent dropdown arrow to the side of the cell?

Thanks, Bob

Of course, Bob, this is easy - just use the Combobox control instead of the Data Validity
