Collapsing Categories

Screenshots

Collapsing Categories creates an expandable list of categories and subcategories. It can also expand to show posts. The primary usage is as a widget, but you can also use the code in your theme manually if you wish (see installation instructions) Options Style options can be set via the settings panel. All other options can be set from the widget panel. If you wish to insert the code into your theme manually instead of using a widget, you can use the following options. These options can be given to the collapsCat() function either as an array or in query style, in the same manner as the wp_list_categories function. $defaults=array( 'showPostCount' => true, 'inExclude' => 'exclude', 'inExcludeCats' => '', 'showPosts' => true, 'showPages' => false, 'linkToCat' => true, 'olderThan' => 0, 'excludeAll' => '0', 'catSortOrder' => 'ASC', 'catSort' => 'catName', 'postSortOrder' => 'ASC', 'postSort' => 'postTitle', 'expand' => '0', 'defaultExpand' => '', 'postTitleLength' => 0, 'accordion' => 0, 'catfeed' => 'none', 'taxonomy' => 'category', 'showPostDate' => false, 'postDateAppend' => 'after', 'postDateFormat' => 'm/d', 'useCookies' => true, 'showTopLevel' => true, 'postsBeforeCats' => false, 'expandCatPost' => true, 'debug'=>'0' ); inExclude Whether to include or exclude certain categories ‘exclude’ (default) ‘include’ inExcludeCats The categories which should be included or excluded showPages Whether or not to include pages as well as posts.

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) accordion When set to true, expanding one category closes all others at that level catfeed Whether to add a link to the rss feed for a category.

Possible values: ‘after’ (default) ‘before’ postDateFormat What format the post date is in. This uses the standard php date formatting codes useCookies When true, expanding and collapsing of categories is remembered for each visitor. When false, categories are always display collapsed (unless explicitly set to auto-expand). Possible values: 1 (true) (default) 0 (false) showTopLevel When set to false, the top level category will not be shown. This could be useful if you only want to show subcategories from one particular top-level category 1 (true) (default) 0 (false) postsBeforeCats When set to true, posts in category X will be ordered before subcategories of category X 1 (true) 0 (false) (default) expandCatPost When set to true, any category to which a post is assigned will automatically be expanded on a single post page. 1 (true) (default) 0 (false) showEmptyCat When set to true, empty categories are shown 0 (false) (default) 1 (true) 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 collapsCat('animate=1&catSort=ASC&expand=3&inExcludeCats=general,uncategorized') This will produce a list with: * animation on * categories shown in alphabetical order * using images to mark collapsing and expanding * exclude posts from the categories general and uncategorized Demo I use this plugin in my blog at http://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 categories will still work (which is the default behavior in wordpress anyways)
