layui的select不顯示

<select name="choice" lay-filter="choice">
    <option value="">請選擇</option>
    <option value="year" title="查看某年數據">年份選擇</option>
    <option value="month" title="查看某月數據">年月選擇</option>

解決辦法

layui.use(['apexcharts','jquery', 'laydate', 'febs', 'form', 'eleTree', 'validate','transfer','layer','util'], function () {
        var $ = layui.jquery,
            laydate = layui.laydate,
            layer = layui.layer,
            febs = layui.febs,
            util = layui.util,
            form = layui.form,//這一句
            eleTree = layui.eleTree,
            validate = layui.validate,
            $view = $('#paper-chart');
        form.render();//添加這一句
