You can use a default "Menu" module on your template or page to add a breadcrumbs style menu.
Step-by-step instructions
Step 1: Add a Menu module
Add a "Menu" module module to your template or page. On a template you can do this by clicking on the "+ Add" tab on the right-hand sidebar and searching for the "Menu" module:
On a page you can click on the plus sign (+) icon in the left-hand sidebar and search for the "Menu" module:
Step 2: Place the module and open its settings
Drag the module to wherever you would like it to appear in your template or page and then click on it to open the module settings. These will appear under the "Edit" tab on the right-hand sidebar:
Step 3: Update the module settings
Scroll down in the module settings, select your the Menu you would like to use and set the "Advanced menu type" to "Breadcrumb style path menu (uses horizontal flow)":
You can leave the other settings as they appear, although I've chosen to set the Max levels to 10 and disable flyouts above.
Step 4: Publish your template or page
Click on "Publish changes" on the top right-hand corner of your template or "Publish" on the top right-hand corner of your page and you should be ready to go!
