i need make drop down 1 <li> element 

<div class="head-nav">                 <span class="menu"></span>                 <ul class="cl-effect-15">                     <li><a href="index.php" data-hover="home">home</a></li>                     <li><a href="about.php">about</a></li>                     <li><a href="contact.php" data-hover="contact">contact</a></li>                     <li><a href="#" data-hover=" "> </a></li>                     <li><a href="3" data-hover=" "> </a></li>                     <li class="pull-right"><a href="#" data-hover="more option" tabindex="-1">more options</a>                             <ul class="dropdown-menu">                                 <li><a href="#" data-hover=" ">one</a></li>                                 <li><a href="3" data-hover=" ">two</a></li>                             </ul>                     </li>                     <li class="pull-right"><a href="logout.php" data-hover="logout">logout</a></li>                     <div class="clearfix"> </div>                 </ul>             </div>

but sub menu doesn't opens

using bootstrap v3.1.1

note : adding after jquery doesn't works

you have use 

<li class="dropdown">    <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">dropdown <span class="caret"></span></a>     <ul class="dropdown-menu" role="menu">        <li><a href="#">action</a></li>        <li><a href="#">another action</a></li>        <li><a href="#">something else here</a></li>        <li class="divider"></li>        <li><a href="#">separated link</a></li>        <li class="divider"></li>        <li><a href="#">one more separated link</a></li>     </ul> </li>

in code, miss class "dropdown" li tag. correct dropdown, have use sintax:

<li class="dropdown">  <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">item dropdown <span class="caret"></span></a>   <ul class="dropdown-menu" role="menu"> <!--- put menu-item here -->   </ul> </li>

you can refer bootstrap documentation here

the issue causing missing of data-toggle="dropdown" in tag a
