ActiveMenu is initially a mouse-reactive button. When the button is clicked, a menu containing unlimited entries appears below it. Each entry on the menu is mouse-reactive and can link to a different URL, each having its own parameters for defining frame-target and status-bar message. Clicking the main button a second time closes the menu. If you change your mind after clicking a menu-entry, drag the pointer out of the menu to cancel the action.

All colors and font variables are user-definable. Spacers can be placed on the menu to divide entries into groups. The applet is easily resized to cater for longer text-strings or a larger font for the button-label, and is capable of counting your menu-entries and setting the correct length for the menu automatically. There is also optional sound support.
