RadioField and CheckboxesField giving custom widget{attrs} not only to intself but also to every child

[yarickprih]

If you override RadioField's or CheckboxesField's widget attrs and give it a class, the class appears not only in a parent element but also in every child.

<ul id="id_select-multiple" class="checkbox-fields">
    <li><label for="id_select-multiple_0"><input type="checkbox" name="select-multiple" value="Option 1"
                class="checkbox-fields" id="id_select-multiple_0">
            Option 1</label>
    </li>
    <li><label for="id_select-multiple_1"><input type="checkbox" name="select-multiple" value="Option 2"
                class="checkbox-fields" id="id_select-multiple_1">
            Option 2</label>
</ul>

In this case, i gave a CheckboxesField "checkbox-fields" class attr and it appears in parent ul tag and in every child input tag

I think you can use child combinator selector - > in css for styling until the bug is not fixed.
