I've got a django-based tool (https://tools.wmflabs.org/spi-tools-dev/spi/) which uses selectize.js.  For simple cases, everything works fine.  But, if I click on the drop-down, delete the contents, type in a new value, and submit the form (Sock Info button), the submitted form data has case_name blank.

Is there anybody here who is familiar with javascript and/or selectize.js who would be willing to point me in the right direction?
