To autocomplete city area in search refine page

[trsakhilk]

Hi guyzz,

I have added the City Areas field to the search refine section of osclass. Howver i want to show the list of the city areas when someone starts typing in the city area field.

Example: As soon as someone types "b" in the city area then i want to show the list of city areas starting with "b". Again typing "ba" should show list of city areas starting with "ba" and so on.
Please help me guys as it is very important.

Thanks in advance.
