Filters

Filters allow users to refine visible data by applying structured criteria. They reduce results without modifying underlying data. Filters must be consistent in terminology, placement, and behavior across all products.

When to use

When a dataset or list is large enough that users need to narrow results to find what they need.
When multiple filter criteria can be applied simultaneously.
Do not use filters for permanent data modifications - filters only affect the current view.

Style

Filter labels use short noun phrases that match the attribute being filtered. For example, Owner, Status, Data domain.
Use sentence case for all filter labels and option values.
Show the active filter count when filters are collapsed. For example, Filters (3).
Use consistent terminology across all filter controls in the same view.

Behavior

Apply filters immediately on selection, or provide an explicit Apply button for complex filter sets.
Provide a Clear all or Reset filters action when filters are active.
Persist filter state when users navigate away and return to the same view.
