SimpleTOC – Table of Contents Block

SimpleTOC allows you to configure global settings for your WordPress website. These settings can be enforced globally, overriding any block-level configurations that may exist. To access these settings, navigate to the SimpleTOC section of the WordPress Settings.

Select the block and select “group” in the context menu. Apply “background color”, “link color” and “text color” to this group. SimpleTOC will inherit these styles. You would like to use this styled SimpleTOC group next time you write a post? Convert it to a reusable block.

If you really want to hide a single heading from the table of contents, then add the CSS class “simpletoc-hidden” to a heading block. You can find this field in the same place as the HTML anchor field: In the Block > Advanced sidebar. But first, think about the reason you would like to hide a specific heading. Maybe you would like to remove all headings of a specific depth level. Then there is an option for that in the blocks options in Gutenberg. If you think this heading should not be part of the toc perhaps it is not needed in the post itself?

You can convert your configured SimpleTOC block into a reusable block in Gutenberg. It will keep its settings. This way, you can use your desired settings for each new post by adding the reusable block.

If you add a custom class to the SimpleTOC block in “Advanced” and then “Additional CSS Class(es)” a div with that class will be wrapped around the HTML output.

Use the ‘simpletoc_excluded_blocks’ filter. For example, this code will exclude heading blocks that are inside a column block.

Example:

add_filter( 'simpletoc_excluded_blocks', function ( array $blocks ) {
    $blocks[] = 'core/column';

    return $blocks;
} );

The heavy plus character I used can not be colored with css without hacks. But you can change the icon to something else and change the color of the new icon.

.simpletoc-collapsible::after {
    content: "✖";
    color: #e94c89;
}

I don’t see an easy solution at the moment. SimpleTOC is only a block that can be placed in your post. If there was a plugin that adds blocks to every post, then this would be the solution. I think this should be another separate plug-in to keep the code of SimpleTOC clean and … well, simple.
