Javascript, autoload text box while typing

I am trying to do this but keep on failing.

I have a text box. I have also an array of cities, and i want, while typing to display the cities that the user should be 开发者_运维知识库able to select.

Like if the user is typing : Mu the drop down should display Mumbai \n MuMu ... etc Like the Tags below is doing !

Does someone have any ideas in how this can be accomplished ?

There are quite a lot different JQuery plugins for this purpose:
