Filter bar
The bar above a list: the controls that narrow it, the filters in force as removable chips, “Clear filters”, and the count of results — the state kept by the app, in the address.
Web uniquement — React, depuis @krizaka/ui/filter-bar. Bêta : son API peut encore changer à une version mineure.
Quand l’utiliser
- Above a table or a grid people narrow with several criteria at once: status, type, owner, period, a query.
- When the filters must be visible and undoable one by one, and shared in a link.
Quand ne pas l’utiliser
- For one choice among a few views of a list: chips in a single group.À la place : Chip
- For a search alone: a search field.À la place : Search field

Props
FilterBar
The bar of filters above a list: controls, active filters as chips, clear all, the count of results.

results | string | — | The count of results ("42 jobs"), announced politely when it changes. |

A filter's button and its menu of options — checkboxes (several values) or radios (one) — with a count of chosen ones.
| Prop | Type | Défaut | Description |

multiple | boolean | — | Several values (checkboxes, default) or one (radios). One value: the options are radios. |
Accessibilité
- The bar is a
groupnamed bylabel; each chip's remove button is named byremoveLabel(“Remove Status: Failed”). - The count of results is a polite live region: a change of filter is heard without moving the focus.
FilterMenuis a Radix menu of checkbox (or radio) items: their state is announced as they toggle.
Clavier
| Touches | Action |
|---|---|
| Enter / Space / Arrow Down | Opens a filter's menu. |
| Arrow keys | Move between the options of an open menu; Space checks one, the menu stays open. |
| Esc | Closes the menu and returns to its button. |
Bonnes pratiques
- Keep the filters in the address:
readFilterParamson load,writeFilterParams(which resets the page) on change. - Give each active chip the filter's name and value (“Status: Failed”), not the value alone.
- Count the results in
results(“42 jobs”): it is announced when it changes. - Use
FilterMenufor a list of values (checkboxes, or radios withmultiple={false}), aDateRangePickerfor a period.
