# The 10 filters — and how they're shown

Filters are the product's core value ("filtered the way parents think").
Ten primary filters, ordered by how often a parent reaches for them.

## The 10
| # | Filter | Control | Why parents use it | Backend |
|---|---|---|---|---|
| 1 | **Distance** ("within X miles") | slider/select: 5 · 10 · 20 · 50 mi (needs location) | "how far is it with kids in the car?" | ✅ near+radius_km |
| 2 | **Type** (farm, soft play, park, museum, beach, adventure…) | icon category bar (multi-select) | the "what kind of day" decision | ✅ category |
| 3 | **Indoor / Outdoor** | segmented: Any · Indoor · Outdoor | the weather decision | ✅ indoor/outdoor |
| 4 | **Child age** | chips: 0–2 · 3–4 · 5–8 · 9–12 · Teens (multi) | "will it suit MY kids?" | ✅ age |
| 5 | **Price** | segmented: Any · Free · Under £10 · Under £20 | budget call | ✅ free/price_from |
| 6 | **Buggy-friendly** | toggle | the Priya filter | ✅ buggy_friendly |
| 7 | **Baby changing** | toggle | babies = non-negotiable | ✅ baby_changing |
| 8 | **Parking** | toggle | arriving by car with kit | ✅ parking |
| 9 | **Open now / open on day** | toggle + day picker ("open Sunday") | "can we actually go?" | ⏳ v1.5 (needs structured hours) |
| 10 | **Rating** | 4★+ toggle (until reviews: "Most saved") | trust shortcut | ⏳ v2 (reviews) |

**"More filters" drawer** (not in the 10, still available): accessibility /
SEND-friendly, quiet times, dog-friendly, café on site, picnic allowed,
toilets. Accessibility gets promoted as data coverage grows (Maya persona).

## How they're shown

### Mobile (primary)
- **Quick-chip bar** (horizontally scrollable, always visible under search):
  `Indoor · Free · Buggy-friendly · Under 5s · Open now` + a **`Filters (3)`**
  button showing the active count.
- Tapping **Filters** opens a **bottom sheet**: groups in the order above —
  segmented controls for Indoor/Price, chips for Age/Type, toggle rows with
  icons for the booleans, the distance slider with a live label
  ("within 10 miles · 23 places"). Sticky footer: **`Show 23 places`** +
  `Clear all`.
- Active filters render as **removable chips** in the bar (tap ✕ to drop).

### Desktop
Same chip bar; **Filters** opens a centred modal (same groups, two columns).

### Map view
The same quick-chip bar floats over the map; the distance slider doubles as
the **radius ring** around the parent's pin — pins outside the ring fade out.
Results count updates live ("14 places within 10 miles").

### Principles
- Every filter change updates the URL (shareable, SSR-friendly).
- Live result counts before applying (no dead-end zero-result surprises);
  zero-results suggests removing the most restrictive filter.
- Filter state persists for the session; "kids' ages" (profile, v2) pre-sets
  the age filter automatically.
