XF 1.4 Adding gender options to drop down

[saucylost]

How can I add more gender options to be more inclusive?

Please note that I do not want to use the text box add-on. I want the drop downs and to be able to use the gender message indicator script edit in collaboration with it.

Use custom user fields.
