    I do not think there is yet an official way in version 3 to maximise Google Maps info windows as you could with version 2.

    However you can acheive something similar, see code below. I am sorry my example code isn’t very generic – if you require multiple markers you will need to re-write my code to use arrays or object literals or something.

    I hope this helps!
