Struts2 align check box vertical

Normally the struts checkboxlist in struts2 diaply the check boxes horizontally. In most of application we want to
display the check boxes vetrically ie line by line. For aligning this as vertical we have to do as specified below
1) You have to create a directory template in your src folder
2) create a folder with name of the template you want to create (vertical-checkbox)
3) copy the struts-2.1.6/src/core/src/main/resources/template/simple/checkboxlist.ftl file to this directory content of this file is as follows. Before the </@s.iterator> you have to put a <br> tag as I given in this

<#assign itemCount = 0/>
<#if parameters.list??>
<@s.iterator value="parameters.list">
<#assign itemCount = itemCount + 1/>
<#if parameters.listKey??>
<#assign itemKey = stack.findValue(parameters.listKey)/>
<#assign itemKey = stack.findValue('top')/>
<#if parameters.listValue??>
<#assign itemValue = stack.findString(parameters.listValue)?default("")/>
<#assign itemValue = stack.findString('top')/>
<#assign itemKeyStr=itemKey.toString() />
<input type="checkbox" name="${}" value="${itemKeyStr?html}" id="${}-${itemCount}"<#rt/>
<#if tag.contains(parameters.nameValue, itemKey)>
<#if parameters.disabled?default(false)>
<#if parameters.title??>
<#include "/${parameters.templateDir}/simple/scripting-events.ftl" />
<#include "/${parameters.templateDir}/simple/common-attributes.ftl" />
<label for="${}-${itemCount}" class="checkboxLabel">${itemValue?html}</label>


4) <s:checkboxlist list="urlist" name="selectedValues" listKey="id" listValue="descrption" theme="vertical-checkbox"></s:checkboxlist>
this will give you vertical check box list
only difference is that here you have to specify the theme which is same as the directory u have created in the template directory in the src folder of your project
