class ListFilter(object):

    title = None  # Human-readable title to appear in the right sidebar.

    template = 'admin/filter.html'

    def __init__(self, request, params, model, model_admin):

        # This dictionary will eventually contain the request's query string

    .. versionadded:: 1.4

    It is possible to specify a custom template for rendering a list filter::

        class FilterWithCustomTemplate(SimpleListFilter):

            template = "custom_template.html"

    See the default template provided by django (``admin/filter.html``) for

    a concrete example.
