Funciona y se puede montar sin el fw materialize, pero actualmete como yo lo uso, muestro como quedaría el template:

...
        <?php Css::add('materialize'); ?>
        <?php Css::add('material-icons'); ?>
        <?php Css::add('bar'); ?>
        <?php echo Css::inc(); ?>
    </head>
    ...
        <?php View::partial('bar'); ?>
        <?php echo Js::inc(); ?>
    </body>
</html>

bar.css

.bar .buttons
{
    z-index: 2000;
}

.bar .toggle
{
    background: white;
    color: black;
    height: 100%;
    left: 0;
    opacity: 0.95;
    overflow: auto;
    padding: 25px;
    position: fixed;
    top: 0;
    width: 100%;
    z-index: 1100;
}

bar.js

$(function()
{
    /**/
    $('body').on('click', '.toggle-to', function()
    {
        var to = $(this).data('to');
        $(to).toggleClass('hide').siblings('.toggle').addClass('hide');;
    });
    
    /**/
    $('body').on('click', '.hide-toggle', function()
    {
        $('.bar .toggle').addClass('hide');;
    });
});
