I have a message in an email, and I want to create drop down lists to the right on a couple of lines. After clicking the Developer tab and 'Design This Form', I clicked 'Control Toolbox' and dragged the ComboBox control to the right of a text in the message. However, I do not see an arrow showing up after dragging the ComboBox over. After i right clicked that box and clicked 'Advanced Properties, I see "1-Arrow" next to DropButtonStyle. How can I make this arrow show up? I even added values in properties, but the arrow still doesn't show up.
