Using the JHtmlTabs class in a component

The "J2.5" namespace is a namespace scheduled to be archived. This page contains information for a Joomla! version which is no longer supported. It exists only as a historical reference, it will not be improved and its content may be incomplete and/or contain broken links.

Calling the Class

jimport( 'joomla.html.html.tabs' );

While importing the class in the way above will bring in the class, it will not function as expected. JHtmlTabs cannot be called directly, even after importing. JHtml::_(tabs) must be called as shown in the example below.

Options for JHtmlTabs

onActive: A callback function when a tab is activated with two params. 'title' is the tab itself, and 'description' is the tab content.

onBackground: A callback function when a tab is backgrounded

startOffset: The default tab to start with (zero based index).

useCookie: Whether or not to use cookies to store tab active state. (boolean) (true | false) // This is not a string. Don't use quotes.


$options = array(
    'onActive' => 'function(title, description){
        description.setStyle("display", "block");
    'onBackground' => 'function(title, description){
        description.setStyle("display", "none");
    'startOffset' => 0,  // 0 starts on the first tab, 1 starts the second, etc...
    'useCookie' => true, // this must not be a string. Don't use quotes.
echo JHtml::_('tabs.start', 'tab_group_id', $options);
echo JHtml::_('tabs.panel', JText::_('PANEL_1_TITLE'), 'panel_1_id');
echo 'Panel 1 content can go here.';
echo JHtml::_('tabs.panel', JText::_('PANEL_2_TITLE'), 'panel_2_id');
echo 'Panel 2 content can go here.';
echo JHtml::_('tabs.end');
