title: django-taggit - display existing tags on the django-admin add record page
body: <p>I have created a test vlog application using django/python and <a href="https://github.com/alex/django-taggit" rel="nofollow noreferrer">django-taggit</a>.</p>
  
  <p>The vlog and tags are working as they should.</p>
  
  <p>However, I want to list all the existing tags in the django-admin interface for new and updated vlog entries - similar to displaying the tags as a filter on the django-admin list page.</p>
  
  <p>This will make the selection of new or existing tags for each new or updating vlog entry that much easier.</p>
  
  <p>Here is what I mean by adding the tags as <code>help-text</code> on the tags input field:</p>
  
  <p>My models.py code:</p>
  
  <pre><code>class VlogDetails(models.Model):
      ....
      vlog_video_image_url = models.URLField(null=False, blank=False, max_length=250, unique=True, help_text='http://img.youtube.com/vi/You_Tube_URL/0.jpg')
      ....
      tags = TaggableManager(help_text='List all the available tags here.')
  </code></pre>
  
  <p>Here is the django-admin input form interface:</p>

  <p>Is it possible to display the existing tags in another manner on the new / edit django-admin page?</p>
  
  <p>I have already listed the existing / existing tags on the django-admin list page as a filter as shown below. This filter display does not display on the new / update input forms.</p>
  
  <p>django-admin filter code:</p>
  
  <pre><code>class VlogDetailsAdmin(BaseDetailsAdmin):
  ....
      list_filter = [
          'vlog_date_published',
          'tags',
          'vlog_timestamp_added',
          'vlog_timestamp_updated'
      ]
  </code></pre>

  <p>I have tried several things but none work and I cannot find any related ideas in the docs. Any suggestion would be appreciated. Thanks.</p>
