Hidden dimensions

You prevent a dimension from appearing in the navigation controls by designating it as a hidden dimension.

Hidden dimensions, like regular dimensions, are composed of dimension values that allow the user to refine a set of records. The difference between regular dimensions and hidden dimensions is that regular dimensions are returned for both navigation and record queries, while hidden dimensions are only returned for record queries and dimension search.

In cases where certain dimensions in an application are composed of many values, marking such dimensions as hidden improves Dgraph performance to the extent that queries on large dimensions are limited, reducing the processing cycles and amount of data the Dgraph must return.
