(Quick Reference)
nav:breadcrumb
Purpose
Renders a
<ul> breadcrumb trail a scope within your
navigation structure.
This works much like the
menu tag except it renders only the items on the current activation path to represent the "location" the user is currently at in the navigation structure.
Example
<nav:breadcrumb/><%-- You may have different styling for the top vs. footer breadcrumb --%>
<nav:breadcrumb id="top-breadcrumb"/>
<nav:breadcrumb id="bottom-breadcrumb"/><%-- Custom rendering without ul wrapper --%>
<div class="breadcrumb">
<nav:breadcrumb custom="true">
<p:callTag tag="p:smartLink" attrs="${linkArgs}"/>
<g:if test="$">
»
</g:if>
</nav:breadcrumb>
</div>Note that with custom rendering the outer
<ul> is
not written out for you, you can write out entirely custom HTML.
