Disabling blocks

WordPress blocks are a powerful tool to create content in the WordPress editor. However, sometimes you might want to disable certain blocks. There are WordPress core blocks and wp-lemon blocks, and both can be disabled. It is possible to disable certain blocks, or make a specific allow list of blocks that can be used.

Wp-lemon blocks

Filtering the blocks is done by using the wp-lemon/filter/blocks filter. This filter works as an allow list, meaning that only the blocks that are in the array will be allowed.

add_filter(
	'wp-lemon/filter/blocks',
	function ($blocks) {
		return [
			'logo',
			'node-overview',
			'widgets',
			'widget',
		];
	}
);

You can also use this accent same hook to create a deny list, by unsetting the blocks you want to disable. This means that all blocks are allowed, except the ones that are unset.

add_filter(
	'wp-lemon/filter/blocks',
	function ($blocks) {

		$to_remove = [
			'contact-cta',
			'circle-text',
			'contact-bar',
			'color-block'
		];

		$blocks = array_diff($blocks, $to_remove);
		return $blocks;
	}
);

Core blocks

Also for core blocks we've created a hook in wp-lemon. This hook again works as an allow list, specifically for core blocks.

add_filter('wp-lemon/filter/core-blocks-to-allow',
	function ($blocks) {
		return [
			'core/paragraph',
			'core/list',
			'core/heading',
		];
	}
);

To create a deny list for core blocks, you'll have to use another hook:

add_filter(
	'wp-lemon/filter/blocks-to-remove',
	function ($blocks) {
		$extra_blocks_to_remove = ['core/list'];
		return array_merge($blocks, $extra_blocks_to_remove);
	}
);

To see the full list of hooks we've build for you to use, please take a look at the filter documentation.
