css - Bootstrap 4 navbar with 2 rows

Question

I have created a navbar with Bootstrap 4 alpha 6 that has a large brand/icon on the left, and 2 navbar-nav's with links to the right of the icon. One nav has links, and the other nav has icons. It's working exactly as I want except for one thing.

I'd like the 2 navbars to appear in 2 separate rows to the right of the icon. Like this:

------------------------------------------------------
               link link link link  
brand-icon -------------------------------------------
               icon icon icon
------------------------------------------------------

The mobile version will still show the links vertically as it does now. I've tried several different things with flexbox, but can't get it to work.

Here is my code:

<nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse">
    <div class="container">
        <button class="navbar-toggler navbar-toggler-right align-self-center mt-3" type="button" data-toggle="collapse" data-target="#navbarCollapse">
            <span class="navbar-toggler-icon"></span>
        </button>
        <h1 class="py-2 ml-lg-2 mx-3"><a href="#"><i class="fa fa-envelope-open-o fa-lg" aria-hidden="true"></i></a></h1>
        <div class="collapse navbar-collapse ml-lg-0 ml-3" id="navbarCollapse">
            <ul class="navbar-nav">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Product</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Shop</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">About</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Events</a>
                </li>
            </ul>
            <ul class="navbar-nav">
                <li class="nav-item">
                    <a class="nav-link pr-3" href="#"><i class="fa fa-facebook"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link pr-3" href="#"><i class="fa fa-instagram"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link pr-3" href="#"><i class="fa fa-twitter"></i></a>
                </li>
            </ul>
        </div>
    </div>
</nav>

Answer 1

You can use the flex-column flexbox utility class to stack the 2 navs vertically next to the icon. This sets flex-direction: column on the navbar-collapse div so that it's child elements stack vertically.

<nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse">
    <div class="container">
        <button class="navbar-toggler navbar-toggler-right align-self-center mt-3" type="button" data-toggle="collapse" data-target="#navbarCollapse">
            <span class="navbar-toggler-icon"></span>
        </button>
        <h1 class="py-2 ml-lg-2 mx-3"><a href="#"><i class="fa fa-envelope-o fa-lg mt-2" aria-hidden="true"></i></a></h1>
        <div class="collapse navbar-collapse flex-column ml-lg-0 ml-3" id="navbarCollapse">
            <ul class="navbar-nav">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Product</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Shop</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">About</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Events</a>
                </li>
            </ul>
            <ul class="navbar-nav flex-row mb-2">
                <li class="nav-item">
                    <a class="nav-link py-1 pr-3" href="#"><i class="fa fa-facebook"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link py-1 pr-3" href="#"><i class="fa fa-instagram"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link py-1 pr-3" href="#"><i class="fa fa-twitter"></i></a>
                </li>
            </ul>
        </div>
    </div>
</nav>

Here's another variation with the 2 rows and right align search form:

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarCollapse">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand my-auto" href="#">Brand</a>
    <div class="collapse navbar-collapse flex-md-column" id="navbarCollapse">
        <ul class="navbar-nav ml-auto small">
            <li class="nav-item active">
                <a class="nav-link" href="#">Shop</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Products</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Team</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">About</a>

</nav>
