Time：10-29

Please check the codes and let me know , where i made the mistake that submenu of sidebar is not opening on click. Working code to my link is attached.https://codepen.io/TA0011/pen/yLjWwGQ. I tried to do but couldn't, I shall be highly obliged if you can help me in creating submenu of services which is initially kept hidden and i want to display on click by event listener method.

//for sidebar
const sidebar = document.querySelector('#mySidebar')

const toggle = document.querySelector('#sidebar-toggle')

toggle.addEventListener('click', toggleSidebar)

function toggleSidebar(e) {
  toggle.classList.toggle('open')
  sidebar.classList.toggle('open');
}
//for sidebar

//for sidebar submenu
const caretButton = document.querySelectorAll(".caret");

caretButton.forEach((el) =>
  el.addEventListener("click", (event) => {
    const subMenu = event.target.parentElement.querySelector(".sub-menu");
    subMenu.classList.toggle("show");
  })
);

add to your li class='caret'

CodePudding user response：

Add a class to the parent li element

<li >
    <a>
       <span ><i ></i></span>
       Services<span ></span>
    </a>
    <ul >
        <li><a href="">Home</a></li>
        <li><a href="">Home</a></li>
    </ul>
</li>

in the js get the li elements, then in the loop get the .sub-menu child element

const withSubButton = document.querySelectorAll(".withsub");

withSubButton.forEach((el) =>
   el.addEventListener("click", (event) => {
   const subMenu = el.querySelector(".sub-menu");

    subMenu.classList.toggle("show");
  });
);

Prev:Each .nav-link element should have an href attribute
Next:Is there a way to repeat quotation marks at the beginning of each line of text in HTML/CSS?
