<script src-"/media/js/jquery-1.2.6.min.js"></script>

In your settings.py

Add a setting EXCLUDE_CONTENT_TYPES, with the content types to exclude. This step is not necesary, but advisable

EXCLUDE_CONTENT_TYPES = (('auth', 'group'), ('auth', 'messege'), ...)

You can filter too, with this setting

FILTER_CONTENT_TYPES = (('auth', 'group'), ('auth', 'messege'), ...)

SEARCH_MODELADMIN = True

{% block extrastyle %}
  {{ block.super }}
  <link rel="stylesheet" type="text/css" href="{% admin_media_prefix %}css/changelists.css" />
  {% if cl.formset %}
      <link rel="stylesheet" type="text/css" href="{% admin_media_prefix %}css/forms.css" />
      {% url admin:jsi18n as jsi18nurl %}
      <script type="text/javascript" src="{{ jsi18nurl|default:'../../jsi18n/' }}"></script>
  {% endif %}
  {{ media }}
  {% if not actions_on_top and not actions_on_bottom %}
      <style>
      #changelist table thead th:first-child {width: inherit}
      </style>
  {% endif %}
  {{ generic_fk_media }}
{% endblock %}
