-
-        :param select2_options: This is similar to standard Django way to pass extra attributes to widgets.
-            This is meant to override values of existing :py:attr:`.options`.
-
-            Example::
-
-                class MyForm(ModelForm):
-                    class Meta:
-                        model = MyModel

-                :py:meth:`.init_options`. The reason for this is, few options are not compatible with each other
-                or are not applicable in some scenarios. For example, when Select2 is attached to ``<select>`` tag,
-                it can get if it is multiple or single valued from that tag itself. In this case if you specify
-                ``multiple`` option then not only it is useless but an error in Select2 JS' point of view.
-
-                There are other such intricacies, based on which some options are removed. By enforcing this
-                restriction we make sure to not break the code by passing some wrong concotion of options.
