Keeping my search bar viewable when my navbar collapses with twitter bootstrap

问题

I have a nabvar that contains a search field 'navbarSearchQuery'. When the navbar collapses when the screen shrinks to a phone size I want 'navbarSearchQuery' to remain visible in the navbar. Is there something I can do with @media queries to keep it visible or do I have to move it outside the collapsable section in the navbar?

<nav class="navbar navbar-default navbar-fixed-top">
  <div class="container-fluid">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
        <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 hidden-xs" href="/Home">Yoga</a>
    </div>

    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Browse <span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="#">Popular</a>
            </li>
            <li><a href="#">Friends</a>
            </li>
            <li><a href="#">Groups</a>
            </li>
            <li><a href="#">Neighborhoods</a>
            </li>
            <li><a href="#">About <span class="sr-only">(current)</span></a>
            </li>
            <li><a href="#">Contact</a>
            </li>
          </ul>
        </li>
        <li>
          <div class="navbar-form navbar-left">
            <div class="form-group">
              <input type="text" class="form-control" placeholder="Search" id="navbarSearchQuery" name="location">
            </div>
          </div>
        </li>
      </ul>
      @Html.Partial("_LoginPartial")
    </div>
    <!-- /.navbar-collapse -->
  </div>
  <!-- /.container-fluid -->
</nav>

You can create a form inside the navbar-header.

/**Custom**/

.navbar.navbar-custom {
  height: 50px;
  border: none;
}
.navbar-custom .formSearch {
  width: 300px;
  float: left;
  display: block;
  position: absolute;
  padding-top: 7px;
  margin-left: 160px;
}
.navbar-custom .inner-addon {
  position: relative;
}
.navbar-custom .inner-addon .glyphicon {
  position: absolute;
  padding: 10px;
  pointer-events: none;
  color: black;
}
.navbar-custom .left-addon .glyphicon {
  left: 0px;
}
.navbar-custom .left-addon input {
  padding-left: 30px;
}
@media (max-width: 767px) {
  .navbar-custom .formSearch {
    padding-left: 15px;
    width: 70%;
    margin-left: 0;
  }
  .navbar-custom .navbar-collapse {
    background: #f5f5f5;
  }
}

I can put the navbar in the header part but when I shrink the alignment is slightly off. Can this be fixed?

<div class="navbar-header">
  <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
    <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 hidden-xs" href="/Home">Yoga</a>
  <div class="navbar-form navbar-left navbar-search">
    <div class="form-group">
      <input type="text" class="form-control" placeholder="Search" id="navbarSearchQuery" name="location">
    </div>
  </div>
</div>

before and after pics. you can see the button isn't aligned correctly
