使用实例

下面实例 开启了下拉多选（multiple）, 并开启了检索功能（lay-search）。 效果可以参考 在线实例 的 多选+搜索+大小写不敏感 模块

<select name="多选+搜索+大小写不敏感" lay-verify="required" multiple lay-search>
    <option value="">请选择您的兴趣爱好</option>
    <option>sing1</option>
    <option selected>sing2</option>
    <option>SING1-大写</option>
    <option>movie1</option>
    <option selected>movie2</option>
    <option>movie3</option>
    <option>MOVIE4</option>
    <option>swim</option>
    <option>moon</option>
</select>

更多实例参考 在线实例、或 index.html。
