## Data and privacy

This card uses its configured properties and live card data.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `"Availability"` | maxLength: `40` |  |
| `order` | string | `"listed"` | `"listed"`, `"most-free"`, `"least-free"`, `"name"` | listed: as given. most-free or least-free by the free count, closed and unknown last. name: A to Z. |
| `lowPercent` | integer | `20` | minimum: `1`; maximum: `99` | Below this share free, a tile reads filling up. |
| `freeWord` | string | `"free"` | minLength: `1`; maxLength: `12` | The word after the count: free, open, available, vacant. |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `items` | array | `[]` | minItems: `0`; maxItems: `12` |  |
| `items[].name` | string |  | minLength: `1`; maxLength: `40`; Required |  |
| `items[].free` | integer |  | minimum: `0`; maximum: `99999` | How many are free now. Left out, the tile shows a dash. Never more than total when total is set. |
| `items[].total` | integer | `0` | minimum: `0`; maximum: `99999` | The capacity. 0 or left out shows the free count alone, with no bar. |
| `items[].closed` | boolean | `false` |  |  |
| `items[].note` | string | `""` | maxLength: `40` | A line under the name: a zone, a floor, a reason. |
