ListSelect 一般用来实现选择，可以单选也可以多选，和 Radio/Checkboxs 最大的不同是在展现方面支持带图片。

## 基本用法

```schema: scope="body"
{
  "type": "form",
  "api": "/api/mock2/form/saveForm",
  "body": [
    {
      "type": "list-select",
      "name": "select",
      "label": "单选",
      "clearable": true,
      "options": [
        {
          "label": "Option A",
          "value": "a"
        },
        {
          "label": "Option B",
          "value": "b"
        }
      ]
    }
  ]
}
```

## 选项带图片

```schema: scope="body"
{
    "type": "form",
    "api": "/api/mock2/form/saveForm",
    "body": [
      {
        "type": "list-select",
        "name": "select",
        "label": "图片",
        "options": [
          {
            "label": "OptionA",
            "value": "a",
            "image": "https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=3893101144,2877209892&fm=23&gp=0.jpg"
          },
          {
            "label": "OptionB",
            "value": "b",
            "image": "https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=3893101144,2877209892&fm=23&gp=0.jpg"
          },
          {
            "label": "OptionC",
            "value": "c",
            "image": "https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=3893101144,2877209892&fm=23&gp=0.jpg"
          },
          {
            "label": "OptionD",
            "value": "d",
            "image": "https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=3893101144,2877209892&fm=23&gp=0.jpg"
          }
        ]
      }
    ]
}
```
