+
+The ``formfield_changelist_for_dbfield`` method on a ``ModelAdmin`` allows you to 
+override the default formfields used on a changelist page when list_editable is enabled.
+Use this method to override a formfield only on the changelist. For example, to set
+a CSS class for certain fields::
+
+    class MyModelAdmin(admin.ModelAdmin):
+        def formfield_changelist_for_dbfield(self, db_field, **kwargs):
+            field = super(MyModelAdmin, self).formfield_changelist_for_dbfield(db_field, **kwargs)
+            if db_field.name in ('short_field_1', 'short_field_2'):
+                field.widget.attrs['class']='smaller'
+            return field
+
+By default, this method just returns the result of ``formfield_for_dbfield``.
