The collapse effect is not working- bootstrap

I tried to make a button that displays the hidden content when revealed using bootstrap but it's not working. Any Suggestions

<button class="bc2 border-primary bg-primary rounded-2 mt-4 p-1 text-nowrap card-footer text-white" type="button" data-toggle="collapse" data-target="#ho2" aria-expanded="false" aria-controls="ho2">Get Started</button>
                <div class="collapse" id="ho2">
                    <div class="card card-body">
                       Hello World!
                    </div>
                </div>
Solution

  • Changed the data attr to data-bs-*(for BS5).
    If correct BS js file and css file are included it should work.
