Let's learn how to pass information from one state to another within Eggly. We learn how to define a state so that it has parameters in its definition and then read those parameters using the $stateParams service.
How are you forming the URL string? If you are just trying to do something like
localhost:3000/Development, that will not work and will produce the "reloading" result. What you need to do is prepend the actual category name with the "categories" string, like so:
localhost:3000/**categories**/Development. Hope that helps!
