DISCLAIMER: Every Wednesday (or so) someone at NodeOne makes an unprestigious presentation about something related to Drupal. The presentation is mainly for internal use, but we have decided to share recordings of the presentations to anyone interested. They are shared as-is – there screencast is uncut, sometimes interrupted, can contain noises and bad sound capture. They can also contain useful information about Drupal.
Menu tabs are neat ways of extending the standard menu items on a Drupal site. Unfortunately, it is not always obvious how to create your own tabs. But never fear! Here's a brief screencast showing you how to build menu tabs and default menu tabs in Views (though it could also be use in for example Panels).
