Filter

The Filter control filters a dataset by applying a value-based condition on one column (header) from a dataclip, and only lets matching data through to linked controls. It doesn’t transform data itself: it restricts what connected controls see.

Setting	Required	Description
Input type	Yes	How the filter value is provided: Input, Variable, UserId, or Username.
Default value	No	The filter’s initial value, when using the Input type.
Visible	No	Whether the control is shown on the dashboard.

Mappings

Mapping	Required	Description
FilterValue	Depends	The value used for filtering: typically required for the Input type.

Only one condition is supported per control; use multiple Filter controls to combine several conditions.

Events

Event	Description
On update	Triggered when the filter value changes as a result of a mapping update.

Tips

• Use multiple Filter controls to simulate multi-condition filtering.
• Set Visible to false when the filter is static or user-based, and not meant to be changed by the user.
• Prefer UserId or Username for security-related filtering.
• Make sure the selected header’s data type matches the filter value’s type.
