I’d like to introduce the WordPress plugin Easy Table of Contents for displaying table of contents.

Prerequisites

For the table of contents plugin, I used Easy Table of Contents.

You can also find table of contents plugins from Plugin Tag: table of contents.

By the way, I skipped Table of Contents Plus – WordPress Plugin | WordPress.org since its last update was 4 years ago.

Easy Table of Contents Settings

After installation, you just need to customize from the Easy Table of Contents settings page /wp-admin/options-general.php?page=table-of-contents and you’re done.

For this site, I configured it while referring to the following article:

自動的に見出しを目次にしてくれるプラグインEasy Table of Contents | ゆうそうとITブログ

General

Here are the general settings I changed from the defaults:

• Enable Support: Posts
• Auto Insert: Posts
• Position: Before first heading (default)
• Show when: 2 or more headings are present
• Display Header Label: Show header text above the table of contents.
• Header Label: Table of Contents
• Counter: Decimal

Appearance

I customized the appearance appropriately to match the background color, text color, etc. of the WordPress theme I’m using.

Advanced

Since I’m using the WordPress Related Posts plugin that automatically displays related articles, I configured it to exclude only that heading “関連記事” (Related Posts).

• Exclude Headings: 関連記事

That’s all from the Gemba.
