Beginning Drupal 8

Chapter 4 ■ Taxonomy
Figure 4-5. The complete list of terms
At this point we’ve created a vocabulary and the terms that we will use to categorize content. By default,
taxonomy terms are sorted alphabetically, but in some cases you may need them to be sorted differently. For
example, you may have a vocabulary for regions in the United States, with the terms East, Central, Mountain,
and West. If the terms were sorted alphabetically, they would appear as Central, East, Mountain, and West.
You may want the terms sorted in an east-to-west fashion, meaning the order should be East, Central,
Mountain, and West, in which case you would want the order to differ from the default order. You may
reorder the terms by simply clicking and holding the arrows icon to the left of a term and dragging that item
to the position in the list where you want it to appear. Remember to click the Save button after reordering, as
the order is not permanent until you save the list.
We now have to identify which content types will use this vocabulary as a method for categorizing
content, and configure our vocabulary so that it will appear on the content creation screens for those
content types.
Assigning a Taxonomy Vocabulary to a Content Type
Enabling content authors to assign one of the terms to a new piece of content requires that a site
administrator make changes to the content types. The first step is to identify all the content types that you
want to associate with the new vocabulary. You may decide that all content types will use the vocabulary to
categorize the content created on your site, or you may decide the vocabulary is only appropriate for one or
a few content types. For example, if you had a vocabulary that listed terms for event venues (e.g., cafeteria,
gym, courtyard, soccer field, and so on), you might want to restrict which content types could be used. That
vocabulary may only be appropriate for a Calendar event content type and not your Basic page content type.
As an example, let’s update the “Article” content type on the test site to incorporate the ability to tag
content with the type of sport vocabulary. The first step is to click the Manage link in the admin menu at the
top of any page of your site, and then click Structure. Click the “Content types” link to get to the page that
lists the available content types (shown in Figure 4-6).
