How to add new options to customer title field

-- HikaShop version -- : HikaShop [1407241754]
-- Joomla version -- : 3.2.3
-- Browser(s) name and version -- : Firefox

I would like to add additional options to the customer title field. How do I do that?

Hi,

You have to go through the HikaShop menu Display > Custom fields.
Then edit the address_title field and add new values.

Worked Perfectly. Thank you!

I disabled some options (Miss, Ms, Dr), but they still appear on the front end. A customer cannot choose them, but they still show.
How can I make these options disappear?

Thanks Nicolas, I will empty the fields.
So disabling an option is useful when it's temporarily not available, like a size or color.
