Dimensions

Dimension hierarchies can be defined such that one can be hidden under another. An example is U.S. cities and states. There are thousands of cities and this can be confusing to the user. If City is made a child dimension of State then a user will be shown states first. Only after a user narrows the states to a single item does the city dimension now contain all cities for that single state. This functionality is defined by using the “parent” property on the dimension definition.
