        <u-button @click="rightVisible = true">show</u-button>
    </u-linear-layout>
</div>
</template>

<script>

### 抽屉尺寸

```vue
<template>
<div>
    <u-drawer :visible.sync="smallVisible" size="small" title="标题" :placement="placement">
    </u-drawer>
    <u-drawer :visible.sync="normalVisible" size="normal" title="标题" :placement="placement">
   </u-drawer>
   <u-drawer :visible.sync="largeVisible" size="large" title="标题" :placement="placement">
   </u-drawer>
   <u-drawer :visible.sync="autoVisible" size="auto" title="标题" :placement="placement">
        <template #body>
            <u-linear-layout :style="{ width: placement === 'right'?'500px':'', height: placement === 'bottom'?'calc(100vh - 200px)':''}">auto width/height</u-linear-layout>
        </template>
   </u-drawer>
   <u-linear-layout direction="vertical">
    <u-linear-layout gap="small">
            <u-button @click="placement = 'right'">right</u-button>
            <u-button @click="placement = 'bottom'">bottom</u-button>
        </u-linear-layout>

    <u-linear-layout gap="small">
            <u-button @click="smallVisible = true">small</u-button>
            <u-button @click="normalVisible = true">normal</u-button>
            <u-button @click="largeVisible = true">large</u-button>

<script>
export default {
    data() {
        return {
            smallVisible: false,
            normalVisible: false,
            largeVisible: false,
            autoVisible: false,
            placement: 'right'
        };

### 插槽空缺

```vue
<template>
<div>
    <u-drawer :visible.sync="leftVisible" title="标题" :showHead=false :showFoot=false>
    </u-drawer>
    
    <u-linear-layout gap="small">
        <u-button @click="leftVisible = true">empty</u-button>
    </u-linear-layout>
</div>
</template>

<script>
export default {
    data() {
        return {
            leftVisible: false,
        };
    },
};
</script>
```

### blocks效果测试

```vue
<template>
    <div>
        <u-drawer :visible.sync="leftVisible">
            <template #title>
                <u-text text="标题"></u-text>
            </template>

        <u-linear-layout gap="small">
            <u-button @click="leftVisible = true">empty</u-button>
        </u-linear-layout>
    </div>
</template>
<script>
export default {
    data() {
        return {
