I want to be able to click on the accordion question and have the arrow rotate 180 degrees up and then back down if I again click on the question.

I already figured out how to expand the accordion answer on click using javascript so I just have the arrow left.

Can anyone assist?

Here is the html, css, and js code.

<div >


        
        <div >


            <button>
                <h3>Which services do you provide?</h3>
                <i ></i> 

            </button>

<script>
    
 const buttons = document.querySelectorAll('button');

buttons.forEach( button =>{
    button.addEventListener('click',()=>{

          const faq = button.nextElementSibling;
            faq.classList.toggle('show');
            
    })
} )


</script>

I don't know where to start with the javascript. I'm still fairly new with all of this

CodePudding user response：

You'll have to toggle a class on the icon as well:

const buttons = document.querySelectorAll('button');

buttons.forEach(button => {
  button.addEventListener('click', () => {
    const faq = button.nextElementSibling;
    faq.classList.toggle('show');
    button.querySelector('i').classList.toggle('rotate')
  })
})
