The following are some of the main features of C1Tabs that you may find useful:

• Tab Directions
  The C1Tabs is oriented top-horizontal by default. You can easily change the direction to right, left, or bottom.
• Host External Content
  Host external content in a page; display the content of another Web page in your project or the content of a website outside of your project.
• Scrollable
  When there are too many tabs to fit along the width of the tab, the tabs will scroll instead of wrapping if the scrollable option is set to true.
• Add/remove Tabs
  Dynamically add tabs using the addTab function. In addition, you may include a function that will allow each tab to close by clicking on an 'x' on the tabs.
• Animation
  Add transition effects when end-users navigate between tab pages. Select from built-in animations or create your own custom effects.
• Theming
  With just a click of the SmartTag, change the tabs' look by selecting one of the 5 premium themes (Midnight, Aristo, Rocket, Cobalt, and Sterling). Optionally, useThemeRoller from jQuery UI to create a customized theme!
  
• CSS Support
  Use a cascading style sheet (CSS) style to define custom skins. CSS support allows you to match the tab control to your organization's standards.
