How to remove the arrow in dropdown in Bootstrap 4?

Question

I am using Bootstrap 4. I tried to remove the arrow in dropdown.

The answers I found for Bootstrap 3 do not work any more.

The jsfiddle is here.

<div class="dropdown open">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Dropdown
  </button>
  <div class="dropdown-menu" aria-labelledby="dropdownMenu1">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
  </div>
</div>

Answer 1

Simply remove "dropdown-toggle" class from the element. The dropdown will still work if you have the data-toggle attribute as follows

<button role="button" type="button" class="btn" data-toggle="dropdown"> 
    Dropdown Without Arrow
</button>

overriding .dropdown-toggle class styles affects all dropdowns and you may want to keep the arrow in other buttons, that's why this looks to me the simplest solution.

Edit: Keep dropdown class if you want to keep border styling

<button role="button" type="button" class="btn dropdown" data-toggle="dropdown"> 
    Dropdown Without Arrow
</button>
