Richlist Widget plugin will help you to list WordPress categories in widget areas as an Accordion List. There are some cool options like exclude categories, show/hide read more links, limit the number of posts to be displayed in each category etc etc. This is a really simple plugin, and will do the job 🙂

RichList Widget

Shows posts from Categories as an accordion list with click-able titles.

Display posts, pages, and terms alphabetically in a Rolodex-, catalog-, or directory-style list with the AlphaListing plugin!
This plugin includes a block and shortcode for the list, along with a widget for linking to the list from any location on a site. If a letter has no associated pages, the widget will display the letter unlinked, while the list page will omit the letter entirely.
Show posts from any single or multiple post types, including built-in posts and pages. Post types from plugins like WooCommerce products are also supported. Alternatively, display terms such as categories or tags.
This plugin is based on the original A-Z Listing by Lucy (formerly Dani) Llewellyn, which is no longer maintained. Custom templates built for the original plugin may not work reliably with this version. For the most up-to-date example template, see the <a href="https://raw.githubusercontent.com/Lin87/alphalisting/refs/heads/main/templates/a-z-listing.example.php" rel="nofollow ugc">example template</a>.
