Attributes for Blocks

Description

This plugin adds additional advanced inspector controls to Gutenberg blocks that allow to add any custom HTML attributes to the block’s front-end output. This allows you to add inline styles to fine-tune the block’s appearance, set aria attributes to improve your site’s accessibility, add data attributes to integrate with any JavaScript modules or even JavaScript DOM event attributes such as onclick, onchange or onload.

FAQ

How do I add an attribute?

In your selected block’s inspector controls (Block settings) scroll all the way to the bottom and click on “Advanced”. It should contain a section called “Additional attributes”.
Type an attribute name into the “Add attribute” field and press “Add” to add an attribute for the block. A new input with the attribute’s name should appear below, into which you can optionally insert the attribute value.
Example attributes: style, title, target, class, id, onClick, data-*, aria-*.

How does it work?

For regular blocks, attributes are added to the block save content’s root element, meaning they will be rendered only on the front end and not in the editor. For dynamic blocks the attributes are added via render_callback function and they may also be applied in the editor, depending if the block is rendered server or client side.

Does it work for every block?

It should work with normal blocks that render a valid WP Element that can utilize the blocks.getSaveContent.extraProps filter as well as dynamic blocks that utilize a render_callback. Third party blocks that do something unorthodox may not work.
Known unsupported blocks

Disable block support

The afb_unsupported_blocks filter can be used in your child theme’s functions.php file to disable block support for adding additional attributes.

add_filter('afb_unsupported_blocks', function($blocks) {
    $blocks[] = 'core/button';
    return $blocks;
});

What happens when I disable this plugin?

Blocks with custom attributes may become invalid, depending on which attributes you’ve added. From there you can recover the block without the custom attributes by clicking “Attempt Block Recovery” or keep the block with custom attributes as HTML by choosing “Convert to HTML”. If you don’t want to risk blocks becoming invalid you need to remove all custom attributes before disabling the plugin.

Perfect for the feature it adds: block attributes. And it's a really handy feature for developers and anybody who knows enough HTML to edit tag attributes. I appreciate plugins that do something without trying to be all things to all people. This does its thing without fanfare or bloat. And it exceeds expectations with a handy style editor when "style"' is the attribute. Nice touch. Thanks for the handy plugin.

I was busy building a group block variation with a attribute field when I bumped into your plug-in. It just do what I was looking for in a more comprehensive way. This should definitly be native to wp ! Thank's
