Bootstrap-Tooltip im Navbar-Untermenü funktioniert nicht

Question

Ich versuche, Tooltip auf einer Navbar zu verwenden; Es funktioniert gut, wenn es auf einem Menüelement implementiert wird, das keine Untermenüpunkte hat, aber wenn ich versuche, es in einem Untermenüelement zu verwenden, wird es nicht funktionieren.

Mein Navbar Code:

<!-- ============ START NAVBAR =========== --> 
<nav class="navbar navbar-default navbar-fixed-top" role="navigation"> 
    <div class="container"> 
    <div class="navbar-header"> 
     <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> 
     <span class="sr-only">Toggle navigation</span> 
     <span class="icon-bar"></span> 
     <span class="icon-bar"></span> 
     <span class="icon-bar"></span> 
     </button> 
     <a href="#/" class="pull-left"><img src="images/logo.png"></a> 
    </div> 
    <div id="navbar" class="navbar-collapse collapse"> 
     <ul class="nav navbar-nav navbar-right"> 

     <!-- Home Menu -->

     </ul> 
    </div> 
    </div> 
</nav> 
<!-- ============ END NAVBAR =========== --> 

Innerhalb dieses Navbar Code, wird es auf "Nützliche Links" arbeiten (das ist ein Hauptmenüpunkt ist)

<li><a href="#links" data-toggle="tooltip" data-placement="top" title="Hooray!"><b>Useful links </b></a></li> 

Aber wenn ich versuche, es zu benutzen auf "YWMP", welches ein Untermenü ist, wird es nicht;

<li class="dropdown"> 
      <a href="" class="dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><b>Programs </b><b class="caret"></b></a> 
      <ul class="dropdown-menu" id="menu3"> 
      <li> 
       <a href="">Children and Youth <i class="fa fa-caret-right"></i></a> 
       <ul class="dropdown-menu sub-menu"> 
       <li><a href="#mothers">Play Group</a></li> 
       <li><a href="#boys">Boys 2 Men</a></li> 
       <li><a href="#girls">Fun 4 Girls</a></li> 
       <li><a href="#teens">Drop In Cafe</a></li> 
       <li><a data-placement="bottom" data-toggle="tooltip" href="#youth" data-original-title="Youth Workshop Mentoring Program">YWMP</a></li> 
       <li><a href="#backyard">Backyard Sports</a></li> 
       </ul> 
      </li> 

Oh, und hier ist meine jQuery-Code:

$(document).ready(function(){ 
    $('[data-toggle="tooltip"]').tooltip(); 
});

Damit Ihr Tooltip anzuzeigen, benötigen Sie einen title Attribut haben. Ersetzen

<a ... data-original-title="Youth Workshop Mentoring Program">YWMP</a> 

mit

<a ... title="Youth Workshop Mentoring Program">YWMP</a> 

und es wird funktionieren.
