How to implement an arrow down button?

[afe]

Hello,

I want to make a button that will display a list when I click the button. Just like the button behind the Windows Explorer forward button.
Which control should I use?

Thank you.

Code: Select all

Gui, Margin, 0, 0
Gui, Add, Button, w80 section vBack, Back
Gui, Add, Button, ys w17 section vDown, ▾
Gui, Add, Button, w80 ys section vForward, Forward
Gui, Add, ComboBox, ys+1 r15 w160 v ComboBox
Gui, Show
return

Thank you. I also thought about whether it should be a list box or a menu. But I want it to display "history" instead of "menu".
