I've successfully created a list view based on taxonomical term, and showing each node title belonging to it. But I'd like it to group nodes with the same taxonomical term, but I can't find an option. For example:

Currently shows:

  • Animals
    Dog
  • Animals
    Tiger
  • Animals
    Lion
  • Fish
    Cod

Would like to show:

  • Animals
    Dog
    Tiger
    Lion
  • Fish
    Cod

My views has my first field is Taxonomy, the second is Node: Title. I'm filtering by Taxonomy, and sorting by Taxonomy.

The Views 'Group-By' Pack almost does this, displaying nodes groups by taxonomical term in Node or Teaser format, but not in List or table mode.

Can it be done in List mode?

If I understand your question correctly, I think you need to filter by taxonomy: vocabulary

Have you tried that?

Yes, I already filter by taxonomy, which allows me to list only my "animals" taxonomical terms, rather than all the other terms associated with other parts of my Drupal set-up (eg. my "author" terms).

It's just that the view shows the taxonomy term for every node, rather than each taxonomical term just once for each group of nodes, as illustrated in the above,

I do this in a table view, where I added 'taxonomy: all terms' (limited to one vocabulary) as a field, then for the taxonomy field tick 'exclude from display', and in your style just group by 'taxonomy: all terms'. I did a quick test with a List style and I think it works the same.

My problem is that I now want to sort those groups. I set up a sort criterium 'taxonomy weight', but no matter what weight I give the terms, I can't get the term that I want for my first group to appear first in the listing. Ideas?

A possible solution has now been posted by JordiTR #6 (November 6, 2008), see Grouped By Taxonomy Term, List View

Enabling Devel Themer module may cause the grouping of items in a view to stop working.

This has caught me out more than once, so I'm going to add a note here for future people confused by the behaviour. Including myself :)

For those who are coming here with newer versions of Drupal, views offers an option to group by a field. Just click on the settings for your display style and you can select the field which you wish to group by.

First of all alter a contrib module is a big no no in Drupal.
However since we are talking about Drupal 5 I guess it's acceptable.

It's quite dirty but it works.

1. Add a new filter to the taxonomy view file (views_taxonomy.inc) so the filters will look like this:

      'filters' => array(
        'vid' => array(
          'name' => t('Taxonomy: Vocabulary Name'),
          'list' => 'views_handler_filter_vid',
          'operator' => 'views_handler_operator_andor',
          'handler' => 'views_handler_filter_voc',
          'value-type' => 'array',
          'help' => t('This will filter a view to only nodes that contain a term in the associated vocabulary.'),
        ),
        'distinct_tax' => array(
          'name' => t('Taxonomy: Distinct'),
          'operator' => array('=' => 'is'),
          'list' => array('distinct' => 'distinct'),
          'handler' => 'views_handler_filter_distinct_tax',
          'value-type' => 'array',
          'help' => t('This filter ensures that each taxonomy may only be listed once.'),
        ),
      )

2. Create the 'views_handler_filter_distinct_tax' function:

function views_handler_filter_distinct_tax($op, $filter, $filterinfo, &$query) {
  if (!$query->no_distinct) {
    $query->set_distinct();
    $query->add_groupby('term_data.tid');
  }
}

3. Clear caches with the devel module

4. Add the newly created filter to your views
