SimpleTOC – Table of Contents Block

FAQ

How do I add a background color to SimpleTOC using Gutenberg groups?

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.

How to exclude a single heading from the TOC?

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?

I would like to save my SimpleTOC settings as default. Is that possible?

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.

How to add a div tag wrapper to the TOC?

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. You can force this with a filter, too.

Example:

add_filter( 'simpletoc_wrapper_enabled', '__return_true' );

How to allow developers to exclude specific headings programmatically?

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;
} );

How do I change the color of the accordion menu?

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;
}

How do I add SimpleTOC to all articles automatically?

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.
