    [tabOptions]
    Display options for the tabs themselves.
    [position="top"]
    If top (default), the tabs are placed above their content. If bottom, then the opposite.
    [collapse]
    If truthy, tabs will not be rendered if there is only one tab. The content of that tab will simply be rendered instead.
    [stretch]
    If true, then tabs will stretch to fill the available space in their container.
    [columns]
    If specified, the tabs will attempt to arrange themselves in N columns of equal width. This option is not compatible with stretch.
    [labelOptions]
    Display options for the tab labels.
    [alignVertical="center"]
    Vertical alignment of the label with respect to its tab. Options are: center (default) and bottom.
    [contentOptions]
    Display options for the tab contents.
    [fixedContentWidth]
    Width for the tab container in px. Or, if set to true, the tab container will assume the width of the largest tab. By default, the tab container assumes the width of the current tab.
    [fixedContentHeight]
    Height for the tab container in px. Or, if set to true, the tab container will assume the height of the largest tab. By default, the tab container assumes the height of the current tab.
    [alignVertical="top"]
    Vertical alignment of tab contents with respect to the tab container. Useful only alonside fixedHeight.
Returns
  • HTML markup rendering tabs.
