Allow target as custom attribute for Blocks

Hi there,

it is on our list, for now you can do it with some PHP.
For example:

add_filter( 'render_block', function( $block_content, $block ) {
	if ( ! is_admin() && ! empty( $block['attrs']['className'] ) && strpos( $block['attrs']['className'], 'open-new-tab' ) !== false ) {
		$my_search = 'href="';
		$my_replace = 'target="_blank" href="';
		$new_content = str_replace( $my_search, $my_replace, $block_content );
		return $new_content;
	}
	return $block_content;
}, 10, 2 );

Once added select the Headline block and in Advanced > Additional CSS Classes add: open-new-tab

You’re welcome!
