我创建了一个自动完成组件，其中数据源是 localhost solr。一切正常，但我需要以下拉菜单框的格式提供建议，但在我的情况下，它显示为普通列表，没有下拉菜单出现。

这是我的代码，

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="f"  uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h"  uri="http://java.sun.com/jsf/html"%>
<%@ taglib prefix="c"  uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="rich" uri="http://richfaces.org/rich" %>
<%@ taglib prefix="a4j" uri="http://richfaces.org/a4j"%>
