Dynamic Menus for Controls

I want to create an ActiveX control for a web page as a button with a dropdown menu, like those that appear on IE coolbar. I want to be able to press the button for a standard selection or have the dropdown menu appear when the little down arrow buttonm is pressed.
Is it possible to have a menu like this popup on a control?
How can it be done?
Is there a simple way to create this button control?

I also need to make this menu dynamic and set the items and tick items in the menu. Can anyone guide me in the right direction for menus in AvtiveX controls?

Thank you
