Creating Dependent Filters

This topic describes dependent filters.

Dependent Filters combine multiple dashboard filters into a hierarchy of dependent filters that affect each other from parent, to child, to grandchild and so on. When you filter the parent filter, fewer options will be available in the child filter.

Example Use Case

The following example shows how using a dependent filter helps you easily focus information in a dashboard.

This example describes an online travel agency with 250,000 hotels in its database. An agent wants to find a specific hotel, but does not remember its name. To narrow the results, the agent can define a dependent filter. This dependent filter is comprised of four sub-dependent filters defined with the following hierarchy:

 

Note: By default, filters are not dependent. Dependent Filters can be defined only from selection type filters.

To define a Dashboard Dependent Filter:

  1. The top level (most inclusive) filter of the Dependent Filter must first be defined in the usual manner (see Creating Dashboard Filters). This newly added filter then appears on the dashboard.
  2. On the parent filter, click + or click Add a dependent filter.
  3. Define the child filter in the usual manner (see Creating Dashboard Filters). The number of available options for selection in the child filter are less because of the selections in the parent filter. The child filter appears on the dashboard with a down arrow indicating the dependent filter and its parent above.
  4. Repeat this step for each new child filter to create as many sub-levels of Dependent Filters as you need.
