Progression Bar that looks like a breadcrumb

Hi wondering if anyone can help me at all

I want to create a progression bar that looks like a breadcrumb that you find on websites. I have a model that will break down into a number of components, each component will have a specific name.

I would like the progression bar to show the name of each component I click on when breaking down the model (almost like a hierarchy) for example how i would envision it would be something like this when breaking down:

Component1 - Component2 - Component3

I have absolutely no idea where to start on this or even know how to do the code. I would appreciate any help at all.

Thanks

The first thing that came to my mind when reading this was the health bar in the 3d platform tutorial - it uses segments to display health but could easily be modified to show something similar to what you need.
