Parich Accessible Sitemap

Parich Accessible Sitemap adds a sitemap page that people can read: your pages, your posts by category, other content types and taxonomies, archives and authors. Add the Parich Accessible Sitemap block to any page, or use the [parich_sitemap] shortcode.

Built for accessibility (WCAG 2.1 AA)

• The sitemap is a labelled navigation landmark with real headings (you choose the level, 2–6, to fit your page) and nested lists that screen readers announce with their level. No custom widgets to learn.
• A table of contents jumps to each section, and a “Back to contents” link ends every section.
• Visible keyboard focus. Collapsible categories use native <details>/<summary>, so they work with the keyboard and screen readers and need no JavaScript.
• The link to the page being viewed is marked with aria-current.
• Reflows to a 320px-wide screen without horizontal scrolling, and is sized in rem/em for zoom and custom text spacing.
• Tree lines at full strength in Windows contrast themes and with “increase contrast”; a clean printout (no table of contents, collapsed categories printed open).
• The markup is tested with axe-core and in a real browser; the tests and a manual checklist (keyboard, NVDA, zoom) are in the GitHub repository.

Colors and fonts come from your theme, so text contrast is the theme’s to get right.

Thai language support

• Thai translation of the sitemap, the settings page and the block editor, delivered as a language pack from translate.wordpress.org.
• Years in the Buddhist Era (พ.ศ.) on Thai sites, in any date format.
• Thai titles and names in dictionary order. Databases sort words that start with เ แ โ ใ ไ after all others; this plugin sorts them by their first consonant, as a Thai dictionary does (กา เกม ไก่ ขนม …).
• Line spacing that leaves room for Thai vowels and tone marks.

Fast on large sites

• The sitemap is cached and rebuilt automatically when posts, pages, categories or authors change.
• Posts are loaded in batches without their content, so memory stays low however many posts there are.
• Optionally list only the first posts of each category, with a link to the category page for the rest.

On a test site with 5,000 posts, building the sitemap took under a second and serving it from the cache a few milliseconds.

Display

• A tree with connecting lines (default), or plain nested lists (the block’s “List” style, or style="list").
• Collapsible categories, open or closed at first.
• Show everything, or only one kind of content: pages, posts, categories, tags, archives, authors, or any public content type or taxonomy.

Coming from WP Sitemap Page

This plugin started as a fork of WP Sitemap Page 1.9.6 by Tony Archambeau (GPLv2 or later). Its settings are copied the first time this plugin runs. Replace [wp_sitemap_page] shortcodes with [parich_sitemap]; they take the same attributes.

Source code

The complete source, including the block editor code in src/, ships with the plugin and is on GitHub: github.com/parich/parich-accessible-sitemap. Build it with npm install and npm run build.
