Collapsing Links Plugin

This is a very simple plugin that uses Javascript to form a collapsable set of
links in the sidebar for the links (blogroll). Every link corresponding to a
given link category will be expanded.

You can use multiple instances of the widget, each with its own set of options. In this way you could have one set of links for certain categories one place on your page, and another widget with a different set of links somewhere else.

It is based off of the Collapsing Categories and Collapsing Pages plugins.

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 collapsLink() function either as an array or in query
style, in the same manner as the wp_list_links function.

 $defaults=array( 'showLinkCount'=> true , 'catSort'=> 'linkName' , 'catSortOrder'=> 'ASC' , 'linkSort'=> 'linkName' , 'linkSortOrder'=> 'ASC' , 'inExclude'=> 'exclude' , 'inExcludeCats'=> '' , 'expand'=> 0 , 'customExpand' => '', 'customCollapse' => '', 'defaultExpand'=> '', 'animate' => 0, 'nofollow' => true, 'debug' => false ); 

• showLinkCount
  • When true, the number of links in the category will be shown in
    parentheses following the name of the link category
• catSort
  • The order in which link categories should be sorted. Possible values:
    • ‘catName’ the name of the link category (default)
    • ‘catId’ the id of the link category
    • ‘catSlug’ the slug of the link category
    • ‘catOrder’ custom order specified in the links options
    • ‘catCount’ the number of links in each category
• linkSort
  • The order in which link linkegories should be sorted. Possible values:
    • ‘linkName’ the name of the link (default)
    • ‘linkId’ the id of the link
    • ‘linkUrl’ the url of the link
    • ‘linkRating’ the rating assigned to the link
• catSortOrder
  • Whether categories 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)
• linkSortOrder
  • Whether link 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)
• inExclude
  • Whether to include or exclude certain categories
    • ‘exclude’ (default)
    • ‘include’
• inExcludeCats
  • The link categories which should be included or excluded
• 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

• defaultExpand

  • A comma separated list of link category IDs or Slugs which should be
    expanded by default
• animate
  • When set to true, collapsing and expanding will be animated
• nofollow
  • When set to true (default), rel=’nofollow’ tags will be added to links
• 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

collapsLink('animate=true&nofollow=false&expand=3,inExcludeCats=blogroll,lousy-friends') 

This will produce a list with:
* animation on
* no nofollow tags
* using images to mark collapsing and expanding
* exclude links in the categories blogroll and lousy-friends

Demo

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 links will still work (which is the default
behavior in wordpress anyways)

The option to show the number of links currently uses the number stored in the
database, which includes both visible and invisible links. If you have
invisible links, this number will be wrong.

IMPORTANT!
Please deactivate before upgrading, then re-activate the plugin.

Unpackage contents to wp-content/plugins/ so that the files are in a
collapsing-links directory. Activate the plugin in your WordPress Admin
interface — Collapsing Links.

MANUAL INSTALLATION

To use the plugin manually,
change the following here appropriate (most likely sidebar.php):

Change From:

<ul> <?php get_links_list(); ?> </ul> 

To something of the following:

 <?php if( function_exists('collapsLink') ) { collapsLink(); } else { echo "<ul>\n"; get_links_list(); echo "</ul>\n"; } ?> 

You can add parameters to the collapsLink() function as described in the
options section.

WIDGET INSTALLATION

simply go the Presentation > Widgets section and drag over the Collapsing Links Widget.
