+
+		Combobox Plugin
+		- This plugin converts <combobox> elements in the current xml
+		  into <layer> container, scrollarea and textfield elements.
+		- Additionally it's also possible to add and remove combobox
+		  elements also dynamically.
+		- The full xml implementation allows many ways of customizing
+		  for own needs - custom designs/styles, custom functionality.
+
+
+		Syntax for Static XML Code:
+
+			<combobox name="..." design="..." ...any layer settings...>
+				<item name="..." caption="..." onclick="..." />
+				<item name="..." caption="..." onclick="..." />
+			</combobox>
+
+		Syntax for Dynamic XML Code:
+
+		 - Global Actions:
+
+			addComboboxLayer(cbname, design*)
+			removeComboboxLayer(cbname);
+
+		 - Combobox Layer Actions:
+
+			layer[cbname].addItem(caption, onclick)
+			layer[cbname].addNamedItem(name, caption, onclick)
+			layer[cbname].addIdItem(name, caption, onclick);       same as addNamedItem (for combobox.js compatibility)
+			layer[cbname].selectItem(caption)
+			layer[cbname].selectItemByName(name_or_index)
+			layer[cbname].selectIdItem(name_or_index)              same as selectItemByName (for combobox.js compatibility)
+			layer[cbname].removeAll()
+			layer[cbname].openList()
+			layer[cbname].closeList()
+
+		 - Events/Callbacks:
+
+			layer[cbname].onChange
+
+		- Combobox Layer Attributes:
+
+			layer[cbname].item              - krpano Array of the items
+			layer[cbname].selecteditemindex - current selected item index
