## Popis

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`.

## Časté otázky

### 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-*`.

### Why is the input disabled?

When the current user doesn’t have `unfiltered_html` capabilities attributes cannot
be added and all existing attributes are stripped when the post is updated.

### 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](https://plugins.trac.wordpress.org/browser/attributes-for-blocks/trunk/includes/unsupported-blocks.php)

### Usage with Alpine.js

@ prefix in an attribute name is used for „override“ mode in this plugin, for Alpine.
js attributes use `x-on:click` instead of `@click` or use the shorthand syntax with
two `@` characters instead of one: `@@click`.

### 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.

### How do I add unfiltered_html capability to user roles?

You can modify which roles have the `unfiltered_html` capability using custom code
in your theme’s `functions.php` file or via a custom plugin. Only grant this capability
if you trust the current and future users of that role to not do anything malicious.

    ```
    add_action('init', function() {
        if($role = get_role('contributor')) {
            $role->add_cap('unfiltered_html');
        }
    });
    ```

### 󠀁[A must-have plugin that brings true flexibility to the block editor](https://wordpress.org/support/topic/a-must-have-plugin-that-brings-true-flexibility-to-the-block-editor/)󠁿

 [Germán](https://profiles.wordpress.org/germanfrelo/) 17. októbra 2025

Thank you so much for creating this plugin! It adds a level of versatility to the
block editor that WordPress really needed. Being able to easily add custom attributes—
like data-*, aria-*, or other HTML attributes — makes it incredibly useful for developers
and site builders alike. It works exactly as expected, saves tons of time, and feels
lightweight and reliable. Perfect for anyone who wants finer control over blocks
without having to write extra code or rely on complex workarounds. Huge thanks to
the authors for keeping it simple, powerful, and developer-friendly — I truly hope
this continues to be maintained for future WordPress versions. Highly recommended!
