Collapsiblock makes Blocks collapsible so you can show/hide content by clicking on the title of the Block. This is a great way to incorporate accordion style effect for a full node/page or in a sidebar region of your site. Simply create individual Blocks for each section you want to expand and/or collapse and assign them to a specific region and page. Important Note: These instructions are specific to the YaleSites instance of Drupal using the YaleSites Templates with Omega as the base theme.
