## 全屏抽屉

1. 全屏抽屉效果主要分为三个部分，主要有三个类名

2. 第一个类名 `DrawerPage`，就是第一张图总体外部包裹的类名

3. 第二个类名 `DrawerClose`，用来包裹打开抽屉之后关闭部分

4. 第三个类名 `DrawerWindow`，就是打开的抽屉部分了

```vue
<template>
	<view class="bg-gradual-blue">
        // 全屏主体页面
		<scroll-view scroll-y class="DrawerPage" :class="modalName=='viewModal'?'show':''">
			<cu-custom bgColor="bg-gradual-blue" :isBack="true"><block slot="backText">返回</block>
				<block slot="content">全屏抽屉</block>
			</cu-custom>			
			<view class='padding margin text-center'>
				<view class='cu-btn bg-green lg block shadow radius margin-xl' @tap="showModal" data-target="viewModal">
					打开抽屉
				</view>
			</view>
			<view class="cu-list menu card-menu margin-top-xl margin-bottom-xl shadow-lg">

        // 关闭部分
