Map<String, String> map = new HashMap<String, String>();
map.put("2", "選項(xiàng)二");
map.put("3", "選項(xiàng)三");
map.put("4", "選項(xiàng)四");
map.put("5", "選項(xiàng)五");
map.put("6", "選項(xiàng)六");
req.setAttribute("map", map);
List<String> list = new ArrayList<String>();
list.add("4");
list.add("5");
list.add("6");
req.setAttribute("list", list);

2. JSP代碼：

<%@taglib prefix="g" uri="http://www.golpesoft.com" %>
<g:select value="1">
  <option value="0">選項(xiàng)一</option>
  <g:option value="1">這個(gè)被選中</g:option>
  <!-- items必需是集合或者map -->
  <g:options items="${map }"/>
</g:select>
<!--checkValue支持el,可以是集合或者字符串，指定自動(dòng)生成的checkbox哪些被選中 -->
<g:checkboxs checkValue="${list }" items="${map }" name="checkbox"/>
<!-- checkValue只能是字符串，支持el -->
<g:radios items="${map }" name="radio" checkValue="3"/>

3. 生成的html代碼：

<select>
  <option value="0">選項(xiàng)一</option>
  <option value="1" selected="selected">這個(gè)被選中</option>
  <!-- items必需是集合或者map -->
  <option value="3">選項(xiàng)三</option>
<option value="2">選項(xiàng)二</option>
<option value="6">選項(xiàng)六</option>
<option value="5">選項(xiàng)五</option>
<option value="4">選項(xiàng)四</option>
</select>
<!--checkValue支持el,可以是集合或者字符串，指定自動(dòng)生成的checkbox哪些被選中 -->
<div class="checkbox-div"><input type="checkbox" id="checkbox1" name="checkbox" value="3" /><label for="checkbox1">選項(xiàng)三</label></div><div class="checkbox-div"><input type="checkbox" id="checkbox2" name="checkbox" value="2" /><label for="checkbox2">選項(xiàng)二</label></div><div class="checkbox-div"><input type="checkbox" id="checkbox3" name="checkbox" value="6" checked="checked" /><label for="checkbox3">選項(xiàng)六</label></div><div class="checkbox-div"><input type="checkbox" id="checkbox4" name="checkbox" value="5" checked="checked" /><label for="checkbox4">選項(xiàng)五</label></div><div class="checkbox-div"><input type="checkbox" id="checkbox5" name="checkbox" value="4" checked="checked" /><label for="checkbox5">選項(xiàng)四</label></div>
<!-- checkValue只能是字符串，支持el -->
<div class="radio-div"><input type="radio" id="radio1" name="radio" value="3" checked="checked" /><label for="radio1">選項(xiàng)三</label></div><div class="radio-div"><input type="radio" id="radio2" name="radio" value="2" /><label for="radio2">選項(xiàng)二</label></div><div class="radio-div"><input type="radio" id="radio3" name="radio" value="6" /><label for="radio3">選項(xiàng)六</label></div><div class="radio-div"><input type="radio" id="radio4" name="radio" value="5" /><label for="radio4">選項(xiàng)五</label></div><div class="radio-div"><input type="radio" id="radio5" name="radio" value="4" /><label for="radio5">選項(xiàng)四</label></div>
