A breadcrumb trail is a set of links that shows where you are in relation to other pages in the store. You can click any link in the breadcrumb trail to return to the previous page.
The breadcrumb trail can be configured to appear on content pages and on catalog pages. The format and position of the breadcrumb trail varies by theme, but it is usually located just below the header. By default, the breadcrumb trail appears on CMS pages.
General types of bread crumbs
Breadcrumbs can be divided into three main types, which differ in their purpose. The essence and main principles of the implementation of each type of bread crumbs are described below.
This type of breadcrumb is based on the category hierarchy set up on the site. The chains presented tell the user where in the structure they are. In this case, each text link is intended for a page that is one level higher than the previous one.
Men > Tops > Hoodies & Sweatshirts
The advantage of this type is that users can easily see which category level they are in and have easy access to navigation between catalog pages.
History- (or path-) based navigation is similar to the back button in a browser. This allows users to quickly return to the previous pages they have visited without changes.
The advantage of this type is that it is most helpful when customers want to return to a previous page after selecting multiple filters on a category page.
Home > What's New > Gear > Bags
This type of breadcrumb displays the attributes selected on the category page. The main difference from the other types is that the attribute-based breadcrumbs represent the filters and options the customer has selected in the navigation layer for certain products (such as price, quality, and color).
Home > Suits > All Suits > Refined by > Slim Fit
