Bootstrap 4 Nav项目堆叠

Question

我正在尝试制作一个导航栏，其菜单固定在左侧，导航品牌居中，而购物车和搜索图标固定在右侧。但是，当我按比例缩小到移动设备时，右侧堆栈上的图标。我该如何解决？

<div className="container">
  <nav role="navigation" class="navbar navbar-light bg-faded navbar-toggleable-sm">
    <button className="navbar-toggler mr-auto" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                <span className="navbar-toggler-icon" />
              </button>

    <a class="navbar-brand mx-auto" href="/">
                HOMF
              </a>

    <ul class="navbar-nav ml-auto">
      <li class="nav-item">
        <i class="fas fa-search" />
      </li>
      <li class="nav-item">
        <i class="fas fa-search" />
      </li>
    </ul>

    <div className="collapse navbar-collapse" id="navbarSupportedContent">
      <ul className="navbar-nav ml-auto text-center">
        <li className="nav-item">
          <NavLink to="/" className="nav-link">
            MENS
          </NavLink>
        </li>
        <li className="nav-item">
          <NavLink to="/" className="nav-link">
            WOMENS
          </NavLink>
        </li>
        <li className="nav-item">
          <NavLink to="/" className="nav-link">
            KIDS
          </NavLink>
        </li>
      </ul>
    </div>

  </nav>
</div>
