Bootstrap 5 Navbar Dropdown Not Working: How to Fix Data- Attribute Issues?

Navbar Dropdown Not Working in Bootstrap 5: Resolved

When creating a responsive navigation menu with Bootstrap 5, users have encountered issues with dropdown functionality. Despite having the necessary icons and including jQuery, the dropdown menu fails to appear when the navigation or dropdown buttons are clicked.

Solution:

In Bootstrap 5, data- attributes previously used in Bootstrap 4 have been updated to data-bs- to differentiate Bootstrap functionality from other code. This change has impacted the attributes used for JavaScript plugins, including navbar collapse. To ensure proper functionality, replace the data- attributes with data-bs- as follows:

<button class="navbar-toggler" data-bs-toggle="collapse" data-bs-target="#navbar">
    <span class="navbar-toggler-icon"></span>
</button>
