I use a WordPress site to keep notes on a variety of subjects, they are organised as parents / children. I needed a simple way to show them in a nested list that reflected their hierarchy. So I wrote this plugin to do just that.
Once installed it addes a widget that will allow you to select which post type to display. It’s generally handy if you have hierarchical custom post types or a lot of deeply nested pages. On the front end, this adds a script to load in the post list asyncrously – this lets your website load first without having to worry about pulling together the list of all your posts. Onec the site is loaded, then all the posts will load. Another resource saver for you – the posts are organised into their hierarchical order client side. This means the server just spits out an array of posts and sends them to the visitor’s browser. Once they arrive the visitors browser will do the work of orgaisaiton.

Must use Classic Editor plugin – Add to my list of gripes with Gutenberg that it uses the REST API to display the categories, adding nothing to the categories box for the user while rendering the wp_terms_checklist_args filter useless. If you don’t already use the Classic Editor plugin (installed more than 5 million times to date), you’ll have to use it for this plugin to work. I’m looking for a work-around…
Does your list of categories go on and on, making it difficult to scroll to and find what you need? This plugin will collapse groups of subcategories into expandable submenus, which you may open and close as needed, cutting your category list down to a manageable size. Submenus with checked categories are not collapsed (but are collapsible), so you won’t have to hunt for them.
Thanks to scribu for the code from his Category Checklist Tree plugin, which prevents the breaking of the category list heirarchy.
This plugin works with post categories and WooCommerce product categories too. According to users, it works with custom taxonomies!
