How to insert a new tag with chosen module ? I installed the chosen module and its library on my site drupal 7.

I created a custom field in a content type to enter tags (words) within the vocabulary (taxonomy).

Everything is working correctly for the selection of tag between those in vocabulary, but I can not insert new tags if they do not exist.

Any help ?
I believe the Autocomplete Deluxe module aims to solve that problem.

Autocomplete Deluxe is a replacement for Chosen module. It has a similar feel to the Chosen module, but allows you to add new tags/terms.
