This plug-in implements the Windows Extended ComboBox control, and allows you to use three different list styles: ComboBox, DropDownList and SimpleList. You can use any number of lists, with their own options, properties, images, events, etc. The three list styles allow you to add items with images for two states: normal and selected. You can also indentate the items, showing the lists similar to a tree-view control. Add, update, get the total of items, all with the appropriate action editors.
