What is the proper functionality of the data-bs-toggle attribute in Bootstrap 5?

<button data-bs-toggle="collapse" data-bs-target="#navmenu">TOGGLE</button>

<div class="collapse" id="navmenu">
   <div>ONE</div>
   <div>TWO</div>
   <div>THREE</div>
</div>

Can someone explain why the data-bs-toggle attribute only works for the collapse class and not other class names like asd? Why does it successfully toggle with the keyword dropdown in combination with the class name dropdown-menu? How does this logic work differently depending on the class or id specified?

 <div>
        <button data-bs-toggle="dropdown">
          Dropdown link
        </button>
      
        <div class="dropdown-menu">
            <div>ONE</div>
            <div>TWO</div>
            <div>THREE</div>
        </div>
    </div>

Could anyone clarify the specific functionality behind the data-bs-target and data-bs-toggle attributes, particularly when used with classes like collapse and dropdown? Why is the element targeted different for a dropdown menu with the class dropdown-menu instead of just dropdown? The Bootstrap documentation doesn't provide clear explanations.

Seeking an understanding of these concepts. Your insights would be greatly appreciated!

Answer №1

Given that data-bs-toggle requires the built-in components from Bootstrap and specifies which component will toggle, it's important to note that asd is not a recognized component like Dropdown or Collapse.

Answer №2

Make sure to assign the value of the data-bs-target attribute to the desired class! The data-bs-toggle attribute is specifically used for bootstrap functionalities!
