Question

I want to style(css) some bootstrap-tooltip.js tooltips, without affecting all the tooltips. I have tried many different solutions but i allways end up adding a class to the element that triggers the tooltip.

This is what i tried:

$(function(){
  $("[id$=amount]").tooltip({
    trigger: 'manual',
    placement: 'right'
  }).addClass("test"); // <--- This does not help me. Class just ends up 
});                    //      in the trigger element. Se html output 
                       //      from firebug below...

But then the class just ends up in the element that triggers the tooltips:

<input 
     id="list_wishes_attributes_0_amount" 
     class="test"  <!-- The class I tried to add to the tooltip ended up here. -->
     type="text" 
     tabindex="3" 
     size="30" 
     rel="tooltop" 
     name="list[wishes_attributes][0][amount]" 
     min="0" 
     data-original-title="Only numbers please"
/>

How can i assign a custom class for my tooltip, and not the input field that triggers it?

Prior to Bootstrap 4:

$().tooltip({
  template: '<div class="tooltip CUSTOM-CLASS"><div class="tooltip-arrow"></div><div class="tooltip-inner"></div></div>'
})

---

Bootstrap 4:

$().tooltip({
  template: '<div class="tooltip CUSTOM-CLASS" role="tooltip"><div class="arrow"></div><div class="tooltip-inner"></div></div>'
})

---

Bootstrap 5:
They’ve added the ability to add the custom class within the source so its much easier to do.

$().tooltip({
  customClass: 'CUSTOM-CLASS'
})

Pure Javascript:

var exampleEl = document.getElementById('example')
var tooltip = new bootstrap.Tooltip(exampleEl, {customClass: 'CUSTOM-CLASS'})

or in the html:

<a href="http://stackoverflow.com" data-bs-custom-class="CUSTOM-CLASS" title="Some Helpful Info!" role="tooltip">Stackoverflow.com</a>
