The List component is initialized with the wx.LB_SINGLE style 
(wx.wxLB_SINGLE in release 0.7.3.1 which still uses the wxPython.wx 
package). Since there is no option to use a different style you have a 
few options. You can change the List component to use the multiple 
selection style instead and then change the selection methods to handle 
lists instead. You could also create an appcomponents dir in the 
directory you are using for your project, copy the __init__.py and 
list.py files to that directory and then modify the list.py file so the 
component will only be changed for your application. Lastly, you could 
duplicate the list.py component file and create a new component for 
multiple selections.

The demand has been low for having a multi-selection List in the past, 
so I'm not very enthusiastic about adding a style option for 
multi-selection to List since that would probably mean changing the 
selection methods to always handle lists of items instead of dealing 
with a single string. OTOH, it isn't particularly difficult to make the 
component changes and if the change is going to happen it should be 
done soon, so I'm willing to listen to arguments for supporting 
multi-selection both contiguous or not either for List and/or making a 
new component that supports multi-selection.
