Breadcrumbs are a familiar way for navigation in many websites. They are used to show to user the viewed page in the hierarchy of the website. One thing breadcrumbs are limited to is that they only support upwards navigation, meaning, you can use them to go up in the hierarchy, but not sideways or dig deeper.
In my work, I had to come up with a solution for this limitation: I had to use the breadcrumbs for showing pages that are in the same level as the viewed page, as well as the next level. So, this is what I came up with.
