Before you start make sure you have added the page(s) you want to have breadcrumbs on to the sitemap.
If your environment already have an existing breadcrumb menu, please go to step 2.
Step 1. Creating the breadcrumb menu
Go to the menu pane and choose 'Create Menu'.
You now have an empty menu you can start building a breadcrumb structure from! Remember to give your new menu a fitting name so it is easy for others to find it.
Step 2. Add your pages to the breadcrumb menu.
Click on the 'Widgets' bar to the right to see the different widget options we can use.
Grab the widget 'Group Widget Options' and drag it to your menu as shown on the screenshot below.
For now we will we not do any modifications on the Group Widget Option.
Go back to the 'Widgets' bar and drag the 'Page Link' widget to under the 'Group Widget Options' as shown on the screenshot below.
In this widget you need to do some changes.
- Press the 'Edit the Widget' button (on your widget you have three buttons, edit is the one in the middle).
- Under the tab 'General' you will see the field Label, here you have to type in the name of your page, e.g. 'Contact Us'. This is the name of the breadcrumb the user will see, so remember to also change it for different languages if that is an option in your environment.
- On the bottom of tab 'General' you have the field Site and Page. Choose the correct site and the correct page.
- Click save so you go out of the widget editor and are back in your breadcrumb menu.
- Click 'create menu' if you where not working on an existing menu, if you where, click Save.
Step 3. Add the breadcrumb menu to your page.
Go to the page you want to add the breadcrumb, and based on the structure of the page, add the widget 'Breadcrumb' to your structure.
Click on 'Edit the widget', in the tab 'General' you will see the 'Localization Option' with two fields.
Select the breadcrumb menu you just added your page to.
You will now see the page you added in the 'Page Link' widget in the menu pop up! If it does not, check that you are on the correct page or go back to your menu and check that you added the correct page. 
Save your changes and go to your page - you can now look at your first created breadcrumb!
