Collapsing Pages

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.

Options

If using the manual version, you can pass options either as an array, or using
the query style, just like for other wordpress functions such as
wp_list_pages

 $defaults=array( 'title' => __('Pages', 'collapsing-pages'), 'sortOrder'=> 'ASC' , 'sort'=> 'pageName' , 'defaultExpand'=> '', 'expand' => 0, 'depth' =>-1, 'inExcludePage' => 'exclude', 'linkToPage' => true, 'inExcludePages' => '', 'showPosts' => false, 'animate' => 0, 'useCookies' => true, 'postTitleLength' => 0, 'showTopLevel' => true, 'currentPageOnly' => false, 'debug' => false, ); 

• inExcludePage
  • Whether to include or exclude certain pages
    • ‘exclude’ (default)
    • ‘include’
• inExcludePages
  • The pages which should be included or excluded
• showPosts
  • Whether or not to include posts as well as pages. 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)
