Firefox not displaying caret in Bootstrap dropdown

I am trying to display a caret on the right side of a bootstrap dropdown button inside a button-group. Here is the code snippet I am using:

<div class="span3 well">
    <div class="btn-group btn-block">
        <a class="btn btn-primary dropdown-toggle btn-block" data-toggle="dropdown" href="#">
        New &hellip; <i class="caret pull-right"></i>
      </a>
      <ul class="dropdown-menu">
          <li>1</li>
          <li>2</li>
      </ul>
    </div>
</div>

and

.btn-group .dropdown-toggle {
  padding-left: 10px;
  padding-right: 10px;
}

While it appears correctly in webkit browsers such as Safari and Chrome, Firefox does not display it properly. Can you help me identify if any errors are present and suggest a solution for consistent display across all browsers?

Answer №1

The issue stemmed from the btn-group:

.btn-block .dropdown-toggle {
  padding-left: 10px;
  padding-right: 10px;
}

<div class="span3 well">
  <div class="btn-block"> <!-- <<< At this point, btn-group was removed -->
    <a class="btn btn-primary dropdown-toggle btn-block" data-toggle="dropdown" href="#">
      New &hellip; <i class="caret pull-right"></i>
    </a>
    <ul class="dropdown-menu">
      <li>1</li>
      <li>2</li>
    </ul>
  </div>
</div>

The display is consistent in both Chrome and Firefox.

UPDATE

The root cause is identified here:

.btn-group {
    font-size: 0;
    position: relative;
    vertical-align: middle;
    white-space: nowrap;    // <<< The problem lies within
}

This code is located on line 3438 of bootstrap.css. Resolved with:

<div class="btn-block btn-group" style="white-space: normal;">

Although the appearance of the dropdown elements may need further adjustments, it's assumed you are aware and will address them accordingly.
