Twitter bootstrap dropdown goes outside the screen

I want to implement twitter bootstrap dropdown menu, here's my code:

<span class="dropdown"> 
<a href="#menu1" class="dropdown-toggle" data-toggle="dropdown" ><img class="left" src="/static/img/topmenu_preferences.png" /><b class="caret"></b></a>
<ul class="dropdown-menu">
  <li><a href="#">a</a></li>
  <li><a href="#">b</a></li>
  <li><a href="#">c</a></li>
  <li class="divider"></li>
  <li><a href="#">d</a></li>
</ul>

Dropdown works good, my dropdown is placed next to right edge of the screen and when I click my dropdown-toggle, the list goes outside the screen. It looks like on the screen:

enter image description here

How can i fix it?

adding .pull-right to ul.dropdown-menu should do it

Deprecation Notice: As of Bootstrap v3.1.0, .pull-right on dropdown menus is deprecated. To right-align a menu, use .dropdown-menu-right.

Deprecation Notice 2: As of Bootstrap v5, .dropdown-menu-right is deprecated. For Bootstrap v5, use .dropdown-menu-end.

I encountered this issue recently, and I solved it by addind display="dynamic" to my ngbDropdown (using Angular 12, ngBootstrap 10 and Bootstrap 4):

<div class="row">
  <div class="col">
    <div ngbDropdown display="dynamic" class="d-inline-block dropdown-menu-right">
      <button class="btn btn-outline-primary" id="navbarDropdownForm" ngbDropdownToggle>Sign in</button>
      <div ngbDropdownMenu aria-labelledby="navbarDropdownForm">
        <form class="px-4 py-3">
          <div class="form-group">
            <label for="navbarDropdownFormEmail">Email address</label>
            <input type="email" class="form-control" id="navbarDropdownFormEmail" placeholder="[email protected]"
              autocomplete="username">
          </div>
          <div class="form-group">
            <label for="navbarDropdownFormPassword">Password</label>
            <input type="password" class="form-control" id="navbarDropdownFormPassword" placeholder="Password"
              autocomplete="current-password">
          </div>
          <div class="form-check">
            <input type="checkbox" class="form-check-input" id="dropdownCheck">
            <label class="form-check-label" for="dropdownCheck">
              Remember me
            </label>
          </div>
          <button type="submit" class="btn btn-primary">Sign in</button>
        </form>
        <div class="dropdown-divider"></div>
        <button ngbDropdownItem>New around here? Sign up</button>
        <button ngbDropdownItem>Forgot password?</button>
      </div>
    </div>
  </div>
</div>

If you are using Bootstrap 5, according to documentation:

Dropright: Trigger dropdown menus at the right of the elements by adding .dropend to the parent element.

<div class="btn-group dropend">
 <button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
  Dropright
 </button>
 <ul class="dropdown-menu">
  <!-- Dropdown menu links -->
 </ul>
</div>

I can't leave a comment because my SO level is too low, but I just made sure that the parent container is set to "overflow:hidden" like so (also make sure position is set).

<div style="overflow:hidden;position:relative">
    <span class="dropdown"> 
    <a href="#menu1" class="dropdown-toggle" data-toggle="dropdown" ><img class="left" src="/static/img/topmenu_preferences.png" /><b class="caret"></b></a>
    <ul class="dropdown-menu">
      <li><a href="#">a</a></li>
      <li><a href="#">b</a></li>
      <li><a href="#">c</a></li>
      <li class="divider"></li>
      <li><a href="#">d</a></li>
    </ul>
</div>

in Bootstrap 4 you can use .dropleft

just change to :

<span class="dropleft">

or

add .dropdown-menu-{lg,med,sm,xs}-right to your dropdown-menu 

<div class="dropdown-menu dropdown-menu-sm-right" aria-labelledby="dropdown03">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
</div>

You can use class .dropdown-pull-right with following css:

.dropdown-pull-right {
  float: right !important;
  right: 0;
  left: auto;
}

.dropdown-pull-right>.dropdown-menu {
  right: 0;
  left: auto;
}
<link href="https://maxcdn.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet"/>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/twitter-bootstrap/2.3.1/js/bootstrap.min.js"></script>


<div class="dropdown dropdown-pull-right btn-group">
  <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
  Open Dropdown
  <span class="caret"></span>
  </a>
  <ul class="dropdown-menu">
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
  </ul>
</div>

a solution that does not need modifying the HTML only the CSS is

li.dropdown:last-child .dropdown-menu {
  right: 0;
  left: auto;
}

Its particularly usefull for dynamically generated menus where its not always possible to add the recommended class dropdown-menu-right to the last element

Since Bootstrap v3.1.0 adding .pull-right is deprecated on dropdown menus. A .dropdown-menu-right should be added to ul.dropdown-menu instead. Docs
