The <<.def tabs>> [[macro|Macros]] presents a [[selection of tiddlers|Title Selection]] as a set of tabs that the user can switch between.

The tabs display the <<.field caption>> field of a tiddler if it has one, or the tiddler's title otherwise.

By default the tabs are arranged horizontally above the content. To get vertical tabs, set the <<.param class>> parameter to <<.value tc-vertical>>.

!! Parameters

;tabsList
: A [[filter|Filters]] selecting which tiddlers to include
;default
: The title of the tiddler whose tab is to be selected by default
;state
: The prefix for the title of a [[state tiddler|StateMechanism]] for noting the currently selected tab, defaulting to `$:/state/tab`. It is recommended that this be a [[system tiddler|SystemTiddlers]]
;class
: Additional [[CSS|Cascading Style Sheets]] classes for the generated `div` elements. Multiple classes can be separated with spaces
;template
: Optionally, the title of a tiddler to use as a [[template|TemplateTiddlers]] for transcluding the content of the selected tab

Within the template, the title of the selected tab is available in the <<.var currentTab>> variable.

The <<.vlink currentTiddler>> variable is not affected by the <<.var tabs>> macro.
