+	A dropdown or combo box widget for selecting lists of strings.
+
+	New Attributes
+	==============
+
+	  - items: A List of strings. This can be treated like an ordinary python list.
+	    but only strings are allowed.
+	  - selected: The index of the selected item in the list. Starting from C{0} to C{len(items)-1}.
+	    A negative value indicates, that no item is selected.
+	  - selected_item: The selected string itself, or C{None} - if no string is selected.
+
+	Data
+	====
+	The selected attribute can be read and set via L{distributeData} and L{collectData}.
+	The list items can be set via L{distributeInitialData}.
