For conversion purposes I'm trying to hide the coupon field in the magento cart and only make it visible upon a click. This is adviced by all conversion experts, so it's weird Magento hasn't adopted it yet. But then again, there are a lot of things weird about Magento :-p.
I've found this: Magento hide / show coupon field in cart page on stack exchange with a suggestion. But I'm going to need a little more help.
I tried the solution, but it doesn't work with magento 1.9.2.3. Also the topic is over a year old. I'm not very familiar with javascript, so a detaild instruction would be very helpfull.
I hope there's someone who also thinks this is a good idea and is able to help me achieve this. I'm sure there are a lot of people who want the exact same thing, but don't know how.
All help is very much appreciated. Thank you in advance!
