Anyone looking to disable the Auto Complete drop down that appears when using an input box with the same name more than once can look no further.
In your HTML all you need to do is specify autocomplete="off" on each input box you wish to disable auto-completion.
<input type=”text” name=”email” value=”” autocomplete="off">
However you can also do this “client side”, if you are looking to do this on the actual browser then please stand by and I’ll link to it once I have blogged some instructions.
For now you could follow these instructions by Andy Rathbone.
