CM Tooltip Guide: Despite Being Enabled in the Plugin Settings, There are Some Missing Elements

Missing elements can be a category list, a search box, or a tag cloud, which have been defined to appear on either the Glossary Index Page or Glossary Term page, but are missing despite the plugin settings.
Generally, all elements should be displayed according to the plugin settings, but Sometimes other plugins or theme CSS rules can render some of the HTML invisible by setting the “height” or “width” to 0 or by setting the “display” property to “none” etc, in which case you might find you have some missing elements. The first thing to do to fix this is to check the page’s source, using the Google Chrome’s element inspector or Firefox’s Firebug extension.
