Availability layers
A React component in Beamline's Data & tables category.
A week of bookable start times whose closed times explain themselves: every availability rule (hours, time off, bookings, buffers, rooms, lead time, horizon, an unsynced calendar) is a layer painted under the week; point at a closed time to read every reason with its facts; owners fan the layers apart, see what each rule closes and switch one off to preview the times it costs.
Use it for
- A booking app's week for one service and person or resource, where owners and front desks need to know why a time can't be booked, and which rule costs bookings.
- The host computes the slots and every reason (its rules engine); the part paints, explains, counts and previews.
Not for
- Editing the rules themselves → availability-rule-editor.
- A calendar of events → event-calendar.
Anatomy
- header: whose week, the open count and the rule that alone closes the most, Show layers
- week: day heads, the hour gutter, the stage: a base plane, one plane per rule with its blocks, the result plane with the start times (open pills, closed dots, unknown rings)
- card: the probed time and every reason in rule order with its facts and an edit link; for customers one sentence and the nearest open times
- legend (layers mode): each rule as a sentence, closes N, M only because of this, its preview switch and +N open
States
- flat
- probing (the reasons' layers lit)
- layered (planes fanned apart)
- previewing (a rule off: opened times pop in)
- customer
- unknown (a calendar that didn't sync)
- narrow (one day, day chips)
Keyboard
- Tab enters the week at one start; ↑/↓ move by time within a day, ←/→ to the nearest start on the next day (mirrored right to left)
- A focused closed start shows its card; Tab moves into the card (Edit rule, the nearest open times); Escape in the card returns to the start
- Show layers / Drop back is a toggle button; each rule's switch says whether the rule applies in the preview
Motion
Layers mode tilts the stage and fans the planes apart in depth, the result on top; a hovered rule's plane lifts; dropping back flattens them. Starts a preview opens pop in once. Reduced motion places at once.
Props
| Prop | Type | Default | Description |
|---|---|---|---|
label (required) | string | — | Whose week and for what: "Dana · Cut and colour, 90 min". |
days (required) | AvailabilityDay[] | — | The days drawn, any number of them (a week, a fortnight, three days). |
from | number | — | The hours drawn, 0–24: `to` is the end of the drawn range, so a start must end by it. Default 8 to 19. |
to | number | — | |
layers (required) | AvailabilityLayer[] | — | |
slots (required) | AvailabilitySlot[] | — | |
preview | ((off: string[]) => AvailabilitySlot[]) | — | The week without the given layers, computed by the host: offers each rule's what-if switch. |
audience | "customer" | "owner" | — | "owner" (default) reads the rules and the layered view; "customer" reads one sentence and the nearest open times, and never sees a reason's text (another client's name stays private). |
onPick | ((slot: AvailabilitySlot) => void) | — | An open start chosen. |
formatTime | ((minutes: number) => string) | — | Time in the host's format; default: the locale's hour and minute. |
className | string | — | Classes on the documented visual root; no override by default. |
classNames | Partial<Record<"root" | "header" | "legend" | "slot" | "card" | "stage" | "plane", stri… | — | Classes for the named visual parts; no overrides by default. |
style | CSSProperties | — | Inline styles on the documented visual root; no overrides by default. |
ref | Ref<HTMLDivElement> | — | Receives the documented native target or imperative handle; omitted by default. |
defaultLayered | boolean | — | Open with the layers fanned apart (the owner's "why"): every rule a sheet of glass over the week. Default false. |
