Create a Custom Block Category in the WordPress Block Inserter (Gutenberg)


Are you writing a lot of WordPress block editor (Gutenberg) blocks for just one client? Wouldnt it be good to just group them all together?

Simple, just create a custom block category. In the PHP of your plugin just add the following:

function wholesomecode_wholesome_plugin_block_categories( $categories ) {
    return array_merge(
                'slug'  => 'wholesome-blocks',
                'title' => __( 'Wholesome Blocks', 'wholesome-boilerplate' ),
add_action( 'block_categories', 'wholesomecode_wholesome_plugin_block_categories', 10, 2 );

This will register a custom block category in your block inserter.

Adjust the category argument of the registerBlockType function for your block, like so:

 * Blocks are grouped into categories to help users browse and discover them.
 * The categories provided by core are `text`, `media`, `design`, `widgets`, and `embed`.
category: 'wholesome-blocks',

And there we have it, your block will appear in your newly created block category.
