This is a nested route, using $stateProvider. In fact, you can think of it as a series of route configurations, and trigger the corresponding view when the rules are met. I have seen that if you click on the left side, some product lists will appear on the right side, and then click on the product details, if this is the effect you want. Then, Angular official demo phonecat has it (there is only one for the first layer and the second layer)
