Add Descendants As Submenu Items vs Collapsing Pages

When adding a page, category, or any hierarchical custom post type or taxonomy to your navigation menu (Appearance → Menus), this plugin allows you to optionally automatically add all descendants (children) of that menu item as submenu items. In short, you’ll no longer have to manually maintain submenus when you add a new child page to your site.

This is a very simple plugin that uses Javascript to form a collapsable set of links in the sidebar for the pages. Every page corresponding to a given parent page will be expanded. It is largely based off of my Collapsing Pages and Collapsing Pages plugins.

Default if false linkToPage True, clicking on a parent page title will link to that page (default) False, clicking on a parent page will expand to show sub-pages sort How to sort the pages. Possible values: ‘pageName’ the title of the page (default) ‘pageId’ the Id of the page ‘pageSlug’ the url of the page ‘menuOrder’ custom order specified in the pages settings sortOrder Whether pages should be sorted in normal or reverse order. Possible values: ‘ASC’ normal order (a-z 0-9) (default) ‘DESC’ reverse order (z-a 9-0) expand The symbols to be used to mark expanding and collapsing. Possible values: ‘0’ Triangles (default) ‘1’ + – ‘2’ [+] [-] ‘3’ images (you can upload your own if you wish) ‘4’ custom symbols customExpand If you have selected ‘4’ for the expand option, this character will be used to mark expandable link categories customCollapse If you have selected ‘4’ for the expand option, this character will be used to mark collapsible link categories postTitleLength Truncate post titles to this number of characters (default: 0 = don’t truncate) animate When set to true, collapsing and expanding will be animated useCookies When true, expanding and collapsing of pages is remembered for each visitor. When false, pages are always display collapsed (unless explicitly set to auto-expand). Possible values: true (default) false showTopLevel True – show top level pages (default) False – only display sub-pages and below currentPageOnly True – show only parent and sub pages of the current page False – show all pages (subject to the include or exclude parameters set) (default) debug When set to true, extra debugging information will be displayed in the underlying code of your page (but not visible from the browser). Use this option if you are having problems Examples collapsPage('animate=true&sort=ASC&expand=3,inExcludePages=about') This will produce a list with: * animation on * shown in alphabetical order * using images to mark collapsing and expanding * exclude page about Demo I use this plugin in my blog at http://blog.robfelty.com CAVEAT Currently this plugin relies on Javascript to expand and collapse the links. If a user’s browser doesn’t support javascript they won’t see the links to the posts, but the links to the pages will still work (which is the default behavior in wordpress anyways)
