Overview

Adds configurable and extendable breadcrumbs to the site. Compatible with Symbiote's Multisites and Fromholdio's Configured Multisites fork.

Requirements

SilverStripe CMS 6, see composer.json

Installation

Install the module using composer:

composer require innoweb/silverstripe-breadcrumbs dev-master

Then run dev/build.

Configuration

You can configure whether the home page and pages hidden from the sitetree should be inculded in the breadcrumbs:

Innoweb\Breadcrumbs\Extensions\SiteTreeExtension:
  crumbs_include_home: false # default: true
  crumbs_show_hidden: true # default: false

For a page type you can also disable the crumbs, e.g.:

Your\Project\LandingPage:
  show_crumbs: false # default: true

Usage

By default, the module uses the site tree to generate breadcrumbs.

In your templates, loop over $CrumbList to display the breadcrumbs. You can copy the following code into your template:

<% if $CrumbsList %>
	<nav aria-label="Breadcrumb" class="breadcrumbs">
		<ol itemscope itemtype="https://schema.org/BreadcrumbList">
			<% loop $CrumbsList %>
				<li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
					<% if not $IsFirst %>&gt;<% end_if %>
					<a itemtype="https://schema.org/Thing" itemprop="item" href="$Link"<% if $IsLast %> aria-current="page"<% end_if %>>
						<span itemprop="name">$Title</span>
					</a>
					<meta itemprop="position" content="$Pos" />
				</li>
			<% end_loop %>
		</ol>
	</nav>
<% end_if %>

A page can use the method updateCrumbsList() to add or remove items from the list:

public function updateCrumbsList($list) {
	$tag = $this->getActiveTag();
	if ($tag) {
		$crumb = Crumb::create($tag->Title, $tag->Link());
		$list->push($crumb);
	}
	return $list;
}
