What is the difference between an "autocomplete" and an "autocomplete (Tags style)" widget. These options are present when I add an entity reference field for example.
What is the difference between "Autocomplete" and "Autocomplete (Tags style)" field widget type?
While using entity reference I asked this question and found that: drupal.org/node/241255– herciSep 11, 2015 at 10:46
@herci Sorry but I don't see how this link is relevant. Are you sure you pasted what you meant to paste?– MołotSep 11, 2015 at 11:03
@Mołot you're right. :) The "7" was gone away from end of the link. Correct one is that: drupal.org/node/2412557– herciSep 11, 2015 at 11:05
For one term, there is no difference.
When you increase cardinality (i.e. allow unlimited number of values), with tag style you will put all tags in one textbox, just like you do with tags on this site, and with regular autocomplete you will need to put each one with it's own textbox.
