## 下拉方向


### 自动`auto`

:::demo 
```html
<div style="height: 500px">占位div, 演示效果使用, 底部空间不足时会自动向上展开</div>

<div id="demo1" class="xm-select-demo"></div>

<script>
var demo1 = xmSelect.render({
    el: '#demo1', 
    direction: 'auto',
    data: [
        {name: '水果', value: 1},
        {name: '蔬菜', value: 2},
        {name: '桌子', value: 3},
        {name: '北京', value: 4},
    ]
})
</script>
```

    data: [
        {name: '水果', value: 1},
