deform_select2 provides select2 <http://ivaynberg.github.com/select2/> based widgets for deform
In your Paste Deploy configuration file (e.g. development.ini) add
deform_select2 to the list of pyramid_includes, or add a
this line if a pyramid.includes setting does not exist:
[app:main] ... pyramid.includes = deform_select2
This will put the templates in deform_select2/templates into the
deform search path.
