breadcrumbs

<? $parents = $this->page->navigation_parents(false); ?>
<div class="breadcrumbs hidden-print">
	<div class="container">
		<ol class="breadcrumb">
			<? $why = array(); $home = CMS_Page::findByUrl('/', $why); ?>
			<li><a href="<?= $home->url ?>"><?= $home->navigation_label() ?></a></li>
			
			<? foreach ($parents as $parent) : ?>
				<li><a href="<?= $parent->url ?>"><?= $parent->navigation_label() ?></a></li>
			<? endforeach; ?>
			
			<? $this->render_block('breadcrumb') ?>
			
			<? if (!array_key_exists('breadcrumb', $this->_page_block_content)) : ?>
				<li class="active"><?= $this->page->navigation_label() ? $this->page->navigation_label() : h($this->page->title) ?></li>
			<? endif; ?>
		</ol>
	</div>
</div>

this gist autogenerates breadcrumbs for lemonstand based websites based on the Navigation tab in the CMS. It also allows you to override a page's breadcrumb via the page block section, just add a page block called "breadcrumb" and it'll insert that rather than the autogenerated one for that page
