The module displays a breadcrumb on your site.

Breadcrumbs or breadcrumb trail is a navigation aid used in user interfaces. It gives users a way to keep track of their locations within programs or documents. The term comes from the trail of breadcrumbs left by Hansel and Gretel in the popular fairytale.

Here's an example of how a Breadcrumb might look:

Store Home > Shoes > Men's Shoes > Running Shoes > New Balance 663

You have a few options when it comes to configuring your Breadcrumb:

Title for the store homepage - What should be the title of the first link in the breadcrumb of links Common configurations are "Home" or "Store Home".

Links separator -What character should separate the links in the breadcrumb. Common characters are ">", "»" and "/".

Tag for the last item - By default, the last item in the breadcrumb will appear as a link.  If you don't want it to be hyperlinked, then you can add an HTML tag in this field and the HTML will be replaced.  For example, if you put strong in this field, the last item in the breadcrumb will appear BOLD and will not be a link.

Custom CSS ID - You can apply a CSS ID to the breadcrumb.
