The SimpleDropDownButton component is part of the SyntheticaAddons package. A SimpleDropDownButton is a multiselection button and is mostly placed within a toolbar. Nevertheless it is also possible to use the button with every other Swing container.

A SimpleDropDownButton is very similar to a DropDownButton. The difference is that it is a single button with an integrated arrow icon, which always opens a popupMenu. The default arrow icon is provided by the active Synthetica Look and Feel. You can also set a custom arrow icon or configure the button to display a smaller or bigger arrow.
