The hierarchy filter is a filter type that shows hierarchical data in an expandable tree view ("Category > Brand" or "Continent  > Country > State"). The H-Filter structure can be created by importing an SPSS and an Excel file. As a complement to this, Dapresy has an option of creating the hierarchical filter structure that is derived from the data file, where no other input files except the data file should be needed.

The administrator defines which variables that builds the tree and the hierarchy between the variables. By activating this option from the Project settings tab the administrator will be able to derive the structure from the data.
