I'm using newest Rails 7 and in my app I have implemented cart with turbo similar to the from Episode
, I would like to add some new feature to the checkout show little input field where I can input some discount in percentage for example 20, then my total price should be discounted by 20%.
I wonder how would you implement this functionality ? Should I use simple js script and get id of elements then change it? Or use Stimulus JS - I don't really know this framework ?
Any advice are welcome!
