[SOLVED] Scrollspy active not working with bootsrap 5

Scrollspy active not working with bootsrap 5

I need a help. I used the code from Bootstrap example but it didn't work.

I put data target on Javascript, and i also put data-target on body. The code is full copy from bootstrap-5 scrollspy, but i don't completely understand how to use it. Thank you for your help.

 $('body').scrollspy({ target: '#navbar-example2' });

<body data-target="#navbar-example2">
<nav id="navbar-example2" class="navbar navbar-light bg-light px-3 fixed-top">
      <a class="navbar-brand" href="#">Navbar</a>
      <ul class="nav nav-pills">
        <li class="nav-item">
          <a class="nav-link" href="#scrollspyHeading1">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#scrollspyHeading2">About Me</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#scrollspyHeading3">Skills</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#scrollspyHeading4">My Project</a>
        </li>
      </ul>
    </nav>
    
    <div data-bs-spy="scroll" data-bs-target="#navbar-example2" data-bs-offset="0" class="scrollspy-example" tabindex="0">
      <section id="scrollspyHeading1">
      </section>
      <section id="scrollspyHeading2">
      </section>
      <section id="scrollspyHeading3">
      </section>
      <section id="scrollspyHeading4">
      </section>
    </div>
</body>

Solution

As explained in the Bootstrap 5 docs..

"Scrollable containers and keyboard access If you’re making a scrollable container (other than the ), be sure to have a height set and overflow-y: scroll;..."

For example,

.scrollspy-example {
    position: relative;
    height: 300px;
    overflow: auto;
}
