Hi @vectyr,

You can do so with array_unshift php function. According to the documentation, you can do something like this:

function my_plugin_block_categories( $categories, $post ) {
  if ( $post->post_type !== 'page' ) {
    return $categories;
  }
  $custom_category_one = array(
    'slug' => 'category-dr',
    'title' => __( 'DragonRidge Blocks', 'my-plugin' ),
    //'icon'  => 'admin-home',
  );
  $custom_category_two = array(
    'slug' => 'dr-dashboard',
    'title' => __( 'DragonRidge Dashboard', 'my-plugin' ),
    //'icon'  => 'admin-home',
  );
  $custom_category_three = array(
    'slug' => 'category-home',
    'title' => __( 'DragonRidge Home Page', 'my-plugin' ),
    //'icon'  => 'admin-home',
  );

  array_unshift( $categories, $custom_category_one, $custom_category_two, $custom_category_three );
  return $categories;
}
add_filter( 'block_categories', 'my_plugin_block_categories', 10, 2 );

And you will get this result:

Array
(
    [0] => Array
        (
            [slug] => category-dr
            [title] => DragonRidge Blocks
            [icon] => admin-home
        )

    [1] => Array
        (
            [slug] => dr-dashboard
            [title] => DragonRidge Dashboard
            [icon] => admin-home
        )

    [2] => Array
        (
            [slug] => category-home
            [title] => DragonRidge Home Page
            [icon] => admin-home
        )

    [3] => Array
        (
            [slug] => text
            [title] => Text

        )

            [slug] => design
            [title] => Design
            [icon] => 
        )

    [6] => Array
        (
            [slug] => widgets
            [title] => Widgets
            [icon] => 
        )

    [7] => Array
        (
            [slug] => embed
            [title] => Embeds
            [icon] => 
        )

    [8] => Array
        (
            [slug] => reusable
            [title] => Reusable Blocks
            [icon] => 
        )
