 | |
| 	 *     @type string   $content       Optional. Block HTML markup for the pattern.
 | |
| 	 *                                   If not provided, the content will be retrieved from the `filePath` if set.

 | |

 | |

 | |
| 	 *     @type int      $viewportWidth Optional. The intended width of the pattern to allow for a scaled

 | |

 | |
| 	 *                                   To hide a pattern so that it can only be inserted programmatically,
 | |
| 	 *                                   set this to false. Default true.
 | |

 | |
| 	 *                                   block patterns. Block patterns can be shown on multiple categories.
 | |
| 	 *                                   A category must be registered separately in order to be used here.
 | |
| 	 *     @type string[] $keywords      Optional. A list of aliases or keywords that help users discover
 | |
| 	 *                                   the pattern while searching.
 | |
| 	 *     @type string[] $blockTypes    Optional. A list of block names including namespace that could use
 | |
| 	 *                                   the block pattern in certain contexts (placeholder, transforms).
 | |
| 	 *                                   The block pattern is available in the block editor inserter
 | |
| 	 *                                   regardless of this list of block names.
 | |
| 	 *                                   Certain blocks support further specificity besides the block name
 | |

 | |
| 	 *                                   to be used with. The pattern will only be available when editing one
