angularjs – 如何获得一个完整的高度sidenav与角材料

我使用Angular-Material并实现了一个SideNav菜单。当屏幕尺寸较小时，菜单被隐藏，当单击菜单切换按钮时，菜单从左侧滑出，具有整页高度。当屏幕较大时，菜单显示为固定在左侧，但不是在整页高度。

如何使固定菜单显示为整页高度。
我一直在玩css和其他md属性，但只是无法找到如何。

<div ng-controller="appCtrl" layout="vertical" layout-fill>

<md-toolbar class="md.medium-tall app-toolbar">
    <div class="md-toolbar-tools" ng-click="toggleMenu()">
        <button class="menu-icon" hide-sm aria-label="Toggle Menu">
            <md-icon icon="img/icons/ic_menu_24px.svg">
                <object class="md-icon" data="img/icons/ic_menu_24px.svg"></object>
            </md-icon>
        </button>
        <h2>
            <span>Dev.Material</span>
        </h2>
    </div>
</md-toolbar>

<section layout="horizontal" flex>
    <md-sidenav class="md-sidenav-left md-whiteframe-z2" component-id="menu" is-locked-open="$media('sm')">

        <md-toolbar md-theme="purple">
            <h1 class="md-toolbar-tools">Sidenav Left</h1>
        </md-toolbar>

        <md-content class="md-padding" ng-controller="menuCtrl">
            <p>
                This sidenav is locked open on your device. To go BACk to the default behavior,narrow your display.
            </p>
        </md-content>
    </md-sidenav>

    <md-content flex class="md-padding">
        Some content !!
    </md-content>

和控制器：

(function () { 
'use Strict';

var controllerId = 'appCtrl';
angular.module('app').controller(controllerId,['$scope','$timeout','$mdSidenav',appCtrl]);

function appCtrl($scope,$timeout,$mdSidenav) {
    var vm = this;

    $scope.toggleMenu = function() {
        $mdSidenav('menu').toggle();
    };
};    
})();

(function () { 
'use Strict';

var controllerId = 'menuCtrl';
angular.module('app').controller(controllerId,menuCtrl]);

function menuCtrl($scope,$mdSidenav) {
    var vm = this;

    $scope.close = function() {
        $mdSidenav('menu').close();
    };
};
})();

<ui-view class="ng-scope">
    <div ng-controller="appCtrl" layout="vertical" layout-fill>
        ... your md sidenav code here ...
    </div>
</ui-view>

.ng-scope { height: 100%; }
