# Flap board card

> Canonical HTML: https://screenrig.ai/docs/cards/flap-board/

A split-flap board: a message or a short schedule on tiles that flip to new content, page after page on the wall clock so every screen shows the same page at the same second. Lines are upper-cased and set start, centred or ended; a | pushes the right part of a schedule line to the far end and a ! highlights a row. Everything is a param.

## 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 |
| --- | --- | --- | --- | --- |
| `pageSeconds` | integer | `8` | minimum: `3`; maximum: `120` | How long each page stays. |
| `columns` | integer | `0` | minimum: `0`; maximum: `24` | Tiles across; 0 takes the longest line (6 to 24). |
| `rows` | integer | `0` | minimum: `0`; maximum: `8` | Tiles down; 0 takes the page with the most lines (1 to 8). |
| `align` | string | `"center"` | `"start"`, `"center"`, `"end"` | Where a line without a \| sits in its row. |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `""` | maxLength: `60` | A label above the board; empty shows none. |
| `lines` | array | `["WELCOME"]` | maxItems: `8` | One page of lines. A line is upper-cased; `LEFT\|RIGHT` puts the right part at the far end of the row; a leading `!` highlights the row. |
| `pages` | array | `[]` | maxItems: `12` | Several pages of lines, shown in turn every `pageSeconds`. When present they replace `lines`. |
