It is remarkably easy to extend the 'simple' or 'xhtml' themes to make
s:checkboxlist display vertically. Here's how I did it:
In the root of my web code I have a 'template' folder. Within 'template' I
have a folder named 'my'. Inside 'my' I have checkboxlist.ftl.
checkboxlist.ftl looks like this (minus the license boilerplate):
<#assign itemCount = 0/>
<#if parameters.list?exists>
<@s.iterator value="parameters.list">
<#assign itemCount = itemCount + 1/>
<#if parameters.listKey?exists>
<#assign itemKey = stack.findValue(parameters.listKey)/>
<#else>
<#assign itemKey = stack.findValue('top')/>
</#if>
<#if parameters.listValue?exists>
<#assign itemValue = stack.findString(parameters.listValue)/>
<#else>
<#assign itemValue = stack.findString('top')/>
</#if>
<#assign itemKeyStr=itemKey.toString() />
<tr><td><input type="checkbox" name="${parameters.name?html}"
value="${itemKeyStr?html}" id="${parameters.name?html}-${itemCount}"<#rt/>
<#if tag.contains(parameters.nameValue, itemKey)>
checked="checked"<#rt/>
</#if>
<#if parameters.disabled?default(false)>
disabled="disabled"<#rt/>
</#if>
<#if parameters.title?exists>
title="${parameters.title?html}"<#rt/>
</#if>
<#include "/${parameters.templateDir}/simple/scripting-events.ftl"
/>
<#include "/${parameters.templateDir}/simple/common-attributes.ftl"
/>
/>
</td><td><label for="${parameters.name?html}-${itemCount}"
class="checkboxLabel">${itemValue?html}</label></td></tr>
</@s.iterator>
<#else>
</#if>
This is probably not the ideal way to do this, but it works great for me.
