In Bootstrap 5, clicking inside a dropdown should not cause it to open or close unexpectedly

Check out the code snippet below:

<body>
<div class="dropdown">
  <button class="btn btn-primary dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">
    Dropdown button <i class="bi bi-x inside-button"></i>
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>
<script>
$('.inside-button').on('click', function(e) {
    console.log(new Date());
});
</script>
</body>
</html>

The code shows a bootstrap icon within a button dropdown that triggers a click event (through the class inside-button) to clear the dropdown content.

However, the issue arises where clicking the icon also opens and closes the dropdown. The desired functionality is for the click event to only clear the content without affecting the dropdown's open/close status. How can this be achieved?

Please note that I have extensively searched on Stack Overflow before reaching out, specifically looking for solutions related to Bootstrap 5.

To make the dropdown disappear when you click on your inside-button, you can use the following code:

new bootstrap.Dropdown(".dropdown-toggle").hide();

$('.inside-button').on('click', function(e) {
    console.log(new Date());
    new bootstrap.Dropdown(".dropdown-toggle").hide();
});

    <li><a class="dropdown-item" href="#">Action</a></li>

Answer №2

To simplify the process, consider moving the icon element outside of the button to prevent triggering the dropdown. You can then configure the dropdown to only close when clicked inside using data-bs-auto-close="inside. Keep in mind that this setup may limit closing the dropdown with an outside click. Use CSS to style the alignment of the button text and dropdown accordingly.

An alternative approach would involve adding multiple JavaScript listeners to conditionally trigger the dropdown, although this is not recommended due to complexity.

Below is a basic example that:

  • Includes data-bs-auto-close="inside

  • Moves the icon outside the button as a sibling

  • Adds flex display to their container for centering

  • Adjusts the position of the icon within the button

  • Transfers the button text to a span for customization

    <button class="btn btn-primary dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false" data-bs-auto-close="inside">
      <span style="padding-right: 20px;">Dropdown button</span></button>
      <i class="bi bi-x inside-button" style="margin-left: -43px; color: var(--bs-white);">
