changing the value of the first option in a drop down list

changing the value of the first option in a drop down list

Hi,

I'm using a CMS, so I can't manually change the first value of an item
The first selected word is <Any> and I wanted to make it <All>

so I used this code:

  1. $("option[selected=selected]").val('all');
unfortunately it didn't work, What did I do wrong?

Thanks!
