Agreed. I think an upgrade to the checklistbox tag is in warranted.
Through my searches there are many posts looking for ways to "layout"
the checkboxlist better. Most frustrating on this tag is the actual
checkbox and the label will break lines making this unacceptable from
a UI perspective. Also, many users I saw just wanted a one column
format. I would propose surrounding the <input type=checkbox> and
<label> html elements in a <div> tag (you could even supply an
additional "class" and "style" attribute to the tag). This way a user
could set widths, floats, etc for the div tag. This hack below did
the trick for me. By setting the <div> Class properties: "float" in
combination with "width" you can easily set up one column lists or
fixed width layouts that extend to the next line easily. Would make
this tag much more versatile - especially with just a small
modification.
<#-- Modified checklistbox.tld with surrounding div tag -->
<div class="myCustomDivClass">
<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??>
title="${parameters.title?html}"<#rt/>
</#if>
<#include "/${parameters.templateDir}/simple/scripting-events.ftl" />
<#include "/${parameters.templateDir}/simple/common-attributes.ftl" />
/>
<label for="${parameters.name?html}-${itemCount}"
class="checkboxLabel">${itemValue?html}</label>
<#-- Add ending div tag -->
</div>
