The Complex Filter Widget allows the dashboard designer to empower the end-user to create dynamic filters and apply them to the data in a Board.

A Complex Filter Widget filtering two other widgets

In a typical AppBoard deployment, the dashboard designer pre-configures each Board with a default runtime configuration. This may include filtering the data in a way that is expected to be meaningful to the end-user. Additionally, Actions can be configured that apply specific filters when the User invokes them. For example, when a User clicks on an "alert level" icon, there may be an Action set to filter the Data Collection to only show records where the alert level matches the selection by the User.

In some cases, however, it may be difficult to predict how a User will want to filter the data in a Data Collection. By providing a Complex Filter Widget, the User can create his own custom set of filter rules, and then apply those rules to the Data Collection to update the data being shown in other Widgets on the Board.

In the example screenshot above the board is configured with a complex filter performing a client side filter on the data collection driving the Table and Google Map widgets. Further, as a user the complex filter was used to filter the data collection to where "Country = Australia".
