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

<button  type="button" data-toggle="collapse" data-target="#ho2" aria-expanded="false" aria-controls="ho2">Get Started</button>
                <div  id="ho2">
                    <div >
                       Hello World!
                    </div>
                </div>

CodePudding user response：

If you're using Bootstrap 5, then:

• change data-toggle="collapse" (Bootstrap 4) to data-bs-toggle="collapse" and
• change data-target="#ho2" (Bootstrap 4) to data-bs-target="#ho2".

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