I've downloaded the tagfield module, followed the instructions and code in the Schommer book. The tagfield displays, saves the tags (skills in the book example) but it does not autosuggest. I have tried the latest version from github and the one before that but neither works.

If I look at the source code for the field it says autocomplete="off" see below :

<input type="text" class="text tagField" id="RegistrationMultiForm_Form_Skills" name="Skills" value="" autocomplete="off" href="/index.php/register/Form/field/Skills/suggest" rel=" " />

This suggests that it is a setting somewhere. Should I be setting something in _config.php ? The API isn't that helpful.
