Bootstrap 4：如何在移动设备上获得 2 个切换图标？

Question

有没有办法在 bootstrap 4 的导航栏中获得另一个图标和可折叠下拉菜单？我需要它位于默认切换图标的左侧。

这是我当前的设置（忽略 if 语句）。我试图将搜索放在其自己的可折叠下拉菜单中，在移动设备上有自己的图标，同时在当前下拉菜单中仍然有其他导航项。（我现在可以使用默认的 bootstrap 图标）

试图让我的看起来类似于 monster.com 导航栏，所以看看他们的作为参考。

<div class="container-fluid">
        <nav class="navbar fixed-top navbar-toggleable-md navbar-inverse" style="background-color: #3c763d!important;">

            <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>


            <div id="logo">
                <a class="navbar-brand" href="/">Company Name</a>
            </div>


            <div class="collapse navbar-collapse" id="navbarNav">
                <ul class="navbar-nav mr-auto mx-auto">

                    <form class="form-inline">
                        <input class="form-control" type="text" placeholder="Search for job">
                        <input class="form-control" type="text" placeholder="Location" />
                        <button class="btn btn-seconday " type="submit">Search</button>
                    </form>

                </ul>
                <ul class="navbar-nav">
                    <li class="nav-item"><a href="/post" class="nav-link">Post a Job</a></li>

                    <li v-if="!user_logged" class="nav-item">

Answer 1

将第二个按钮添加到您的 HTML（您可以使用 FontAwesome 图标集作为搜索图标而不是纯文本）。
将 right: 5rem 添加到您的第二个按钮。
将您的导航栏分成两个 divs，具有不同的 ID（用于搜索和导航栏链接）。
向您的按钮添加不同的 data-target 属性。
一切顺利。

.navbar-toggler.navbar-toggler-custom {
  right: 5rem;
}
