bootstrap tooltip keep open on hover

To keep a Bootstrap tooltip open on hover, you can use the data-trigger attribute with the value of "manual" and then use JavaScript to show and hide the tooltip as needed. Here's an example:

<button type="button" class="btn btn-primary" data-toggle="tooltip" data-trigger="manual" title="Tooltip content">Hover me</button>

<script>
  $(document).ready(function() {
    $('[data-toggle="tooltip"]').tooltip();

    $('[data-toggle="tooltip"]').hover(function() {
      $(this).tooltip('show');
    }, function() {
      $(this).tooltip('hide');
    });
  });
</script>

In this example, the data-trigger="manual" attribute is added to the element to prevent the tooltip from automatically hiding. Then, JavaScript is used to show the tooltip when the element is hovered over and hide it when the mouse leaves the element.

Please note that this example assumes you have included the Bootstrap CSS and JavaScript files in your project. Make sure to include them before the above code.

I hope this helps!
