How can I convert "Donation Level" radio buttons into jQuery UI buttons?


I was wondering if someone over there could provide assistance into converting the "Donation Level" radio buttons into jQuery UI buttons, please. (

I followed the code examples on the jQuery website, but to no avail, as the html structure generated by the Fundraising plugin seems to group the buttons in a different way. My code for this:
doesn't work.

I also tried converting the individual input radios into buttons like so:
jQuery(".wdf_reward_choice input[type=radio]").button().click(function(event){event.preventDefault();});
but that doesn't work either.

Any assistance would be greatly appreciated!
