Tabs block

The ever-useful tabs. This component works best with the included JS, but you can use the CSS styling on other tab implementations, like Bootstrap tabs.

Usage

These tabs have been made with accessibility in mind, however tabs should be avoided where content structure avoids the need to use tabs.

Nested tabs are also possible, as demonstrated in the example, however this provides further usability challenges and should be strongly avoided.

Deep linking

A tab can be activated on page load by passing it on the link #vf-tabs__section-tab_id

This is the default behaviour and can be deactivated when invoking vfTabs:

// vfTabs(scope, activateDeepLinkOnLoad)
vfTabs(document, false);

Note: The deep linking feature is not designed with vf-location-nearest compatibility. A vf-location-nearest tab may not respect a deep linked hash url.

Variants

Section 1

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam euismod, tortor nec pharetra ultricies, ante erat imperdiet velit, nec laoreet enim lacus a velit. Nam luctus, enim in interdum condimentum, nisl diam iaculis lorem, vel volutpat mi leo sit amet lectus. Praesent non odio bibendum magna bibendum accumsan.

Section 2

Nullam at diam nec arcu suscipit auctor non a erat. Sed et magna semper, eleifend magna non, facilisis nisl. Proin et est et lorem dictum finibus ut nec turpis. Aenean nisi tortor, euismod a mauris a, mattis scelerisque tortor. Sed dolor risus, varius a nibh id, condimentum lacinia est. In lacinia cursus odio a aliquam. Curabitur tortor magna, laoreet ut rhoncus at, sodales consequat tellus.

Nunjucks syntax

Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.

Using include

You'll need to pass a context object from your code or Yaml file (example), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.


{% set context fromYourYamlFile %}
- or -
{% set context = {
  "exampleMultiColumns": "false",
  "component-type": "block",
  "tabs": [
    {
      "tab_title": "Section",
      "tab_number": 1,
      "tab_heading": "Section 1",
      "tab_content": "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam euismod, tortor nec pharetra ultricies, ante erat imperdiet velit, nec laoreet enim lacus a velit. <a class=\"vf-link\" href=\"#\">Nam luctus</a>, enim in interdum condimentum, nisl diam iaculis lorem, vel volutpat mi leo sit amet lectus. Praesent non odio bibendum magna bibendum accumsan."
    },
    {
      "tab_title": "A Short Section",
      "tab_number": 2,
      "tab_heading": "Section 2",
      "tab_content": "Nullam at diam nec arcu suscipit auctor non a erat. Sed et magna semper, eleifend magna non, facilisis nisl. Proin et est et lorem dictum finibus ut nec turpis. Aenean nisi tortor, euismod a mauris a, mattis scelerisque tortor. Sed dolor risus, varius a nibh id, condimentum lacinia est. In lacinia cursus odio a aliquam. Curabitur tortor magna, laoreet ut rhoncus at, sodales consequat tellus."
    }
  ]
}
 %}
{% include "../path_to/vf-tabs/vf-tabs.njk" %}
                

Using render

This approach is best for bare-bones Nunjucks environments, such as precompiled templates with the Nunjucks slim runtime where include is not be available.

{% render '@vf-tabs', {
  "exampleMultiColumns": "false",
  "component-type": "block",
  "tabs": [
    {
      "tab_title": "Section",
      "tab_number": 1,
      "tab_heading": "Section 1",
      "tab_content": "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam euismod, tortor nec pharetra ultricies, ante erat imperdiet velit, nec laoreet enim lacus a velit. <a class=\"vf-link\" href=\"#\">Nam luctus</a>, enim in interdum condimentum, nisl diam iaculis lorem, vel volutpat mi leo sit amet lectus. Praesent non odio bibendum magna bibendum accumsan."
    },
    {
      "tab_title": "A Short Section",
      "tab_number": 2,
      "tab_heading": "Section 2",
      "tab_content": "Nullam at diam nec arcu suscipit auctor non a erat. Sed et magna semper, eleifend magna non, facilisis nisl. Proin et est et lorem dictum finibus ut nec turpis. Aenean nisi tortor, euismod a mauris a, mattis scelerisque tortor. Sed dolor risus, varius a nibh id, condimentum lacinia est. In lacinia cursus odio a aliquam. Curabitur tortor magna, laoreet ut rhoncus at, sodales consequat tellus."
    }
  ]
} %}

An example deep link loading this anchor will directly activate the neighbouring tab. /vf-tabs#vf-tabs__section--88888

Deep-linked tab

If you see me on page load, the deep link has worked.
