dropdown_filter in django

Hi,

I want to make my custom filter into drop down filter,

class PersonIdFilter(SimpleListFilter):

    title = _('Personid')

    parameter_name ='personid'

    contlist = list(PersonInfo.objects.all())

    def lookups(self, request, model_admin):

        lst = []

        for id in self.contlist:

            lst.append((id.personid,id.personid))

        return tuple(lst)

    def queryset(self, request, queryset):

        if self.value() is None:

            return queryset

        return queryset.filter(personid__exact=self.value())

class PersonAdmin (admin.ModelAdmin):

       list_filter = (PersonIdFilter,)

The above filter is working for me, but I want to convert it into dropdown filter 

I tried with below approach 

Create a class in filters.py 

from django.contrib.admin.filters import AllValuesFieldListFilter

class DropdownFilter(AllValuesFieldListFilter):

    template = 'admin/dropdown_filter.html'

Create a template in templates/admin/dropdown_filter.html

Copied from fiencms

{% load i18n %}

<script type="text/javascript">var go_from_select = function(opt) { window.location = window.location.pathname + opt };</script>

<h3>{{ title }}</h3>

<ul class="admin-filter-{{ title|cut:' ' }}">

{% if choices|slice:"4:" %}

    <li>

    <select style="width: 95%;"

        onchange="go_from_select(this.options[this.selectedIndex].value)">

    {% for choice in choices %}

        <option{% if choice.selected %} selected="selected"{% endif %}

         value="{{ choice.query_string|iriencode }}">{{ choice.display }}</option>

    {% endfor %}

    </select>

    </li>

{% else %}

    {% for choice in choices %}

            <li{% if choice.selected %} class="selected"{% endif %}>

            <a href="{{ choice.query_string|iriencode }}">{{ choice.display }}</a></li>

    {% endfor %}

{% endif %}

And in my admin.py

from receivedata.filters import DropdownFilter

class PersonAdmin (admin.ModelAdmin):

       list_filter = (PersonIdFilter,DropdownFilter)

Error : type object 'PersonIdFilter' has no attribute 'split'

But it did not works for me,please suggest some other way
