无法将搜索框置于引导程序导航栏中心

Question

我有静态引导程序导航栏，并且正试图将搜索框居中。我尝试过的所有东西都不起作用。要么将其置于导航栏下面，要么根本不放置。我现在已经显示，但它显示在左侧的导航栏标题上方，而不是与其他导航栏项目位于同一垂直位置。我尝试过使用表单，导航栏中心和现在的div。他们都没有工作。必须有一些简单的引导类或css我错过了。

<nav class="navbar navbar-default "> 
     <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 class="navbar-brand" href="index.html"><img src="static/img/CAP-Seal-75x75.png" width=50 height=50 ></a> 
      <p style="padding-top:25px;width:120%;"></span>CAWG (TRACS) </p> 
     </div> 
     <div id="search" class="nav navbar-nav navbar-center"> 
     <form class="nav navbar-nav navbar-center" role="search"> 
      <input type="text" class="search form-control input-sm" placeholder="Search" id="sitesearch"> 
       <button type="submit" class="btn btn-xs"><span class="glyphicon glyphicon-search"></span></button> 
       </form> 
     </div> 
     <div id="navbar" class="navbar-collapse collapse"> 
      <ul class="nav navbar-nav navbar-right" style="padding-right:20px;"> 
      <ul class="nav navbar-nav"> 
       <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"> <span class="glyphicon glyphicon-th-list" aria-hidden="true" style="font-size:1.5em;"></span><i class="icon-angle-down"> </i></a> 
        <ul class="dropdown-menu"> 
         <li><a href="#track_modal_realtime" data-toggle="modal">Real Time Tracking</a></li> 
         <li><a id="stop_tracking" href="#">Stop Tracking</a></li> 
         <li><a href="#track_modal_historical" data-toggle="modal">Historical Tracking</a></li> 
         <li><a href="#send_message_modal" data-toggle="modal">Communications</a></li> 
        </ul> 
       </li> 
       <li> 
        <a class="navbar-brand" href="#menu-toggle" id="menu-toggle"><span class="glyphicon glyphicon-resize-full" aria-hidden="true" id="sizeIcon" style="font-size:1.5em;"></span></a></li><!----> 
       <li><a href="#settings_modal" data-toggle="modal"><span class="glyphicon glyphicon-cog" style="font-size:1.5em;" aria-hidden="true"></span></a></li> 
      </ul> 

     </div> 
    </nav> 

有什么建议吗？

谢谢

希望我已经阅读你的问题的权利。如果是这样，你总是可以做这样的事情：

<nav class="navbar navbar-default "> 
<div class="row"> 
    <div class="col-sm-4"> 
    <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 class="navbar-brand" href="index.html"><img src="static/img/CAP-Seal-75x75.png" width=50 height=50 ></a> 
     <p style="padding-top:25px;width:120%;"></span>CAWG (TRACS) </p> 
    </div> 
    </div> 
    <div class="col-sm-4"> 
    <div id="search" class="nav navbar-nav navbar-center"> 
     <form class="nav navbar-nav navbar-center" role="search"> 
     <div class="input-group"> 
      <input type="text" class="search form-control input-sm" placeholder="Search" id="sitesearch"> 
      <span class="input-group-addon" id="basic-addon2"><span class="glyphicon glyphicon-search"></span></span> 
     </div> 
     </form> 
    </div> 
    </div> 
    <div class="col-sm-4"> 
    <div id="navbar" class="navbar-collapse collapse"> 
     <ul class="nav navbar-nav navbar-right" style="padding-right:20px;"> 
     <ul class="nav navbar-nav"> 
      <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"> <span class="glyphicon glyphicon-th-list" aria-hidden="true" style="font-size:1.5em;"></span><i class="icon-angle-down"> </i></a> 
      <ul class="dropdown-menu"> 
       <li><a href="#track_modal_realtime" data-toggle="modal">Real Time Tracking</a></li> 
       <li><a id="stop_tracking" href="#">Stop Tracking</a></li> 
       <li><a href="#track_modal_historical" data-toggle="modal">Historical Tracking</a></li> 
       <li><a href="#send_message_modal" data-toggle="modal">Communications</a></li> 
      </ul> 
      </li> 
      <li> 
      <a class="navbar-brand" href="#menu-toggle" id="menu-toggle"><span class="glyphicon glyphicon-resize-full" aria-hidden="true" id="sizeIcon" style="font-size:1.5em;"></span></a></li><!----> 
      <li><a href="#settings_modal" data-toggle="modal"><span class="glyphicon glyphicon-cog" style="font-size:1.5em;" aria-hidden="true"></span></a></li> 
     </ul> 
     </div> 
    </div> 
    </div> 
</nav>

希望这就是你以后在这里:)
