alpha

This version is in early development and is subject to change and therefore not ready for wide use. There may be other stable versions available.

Bookmark element

Indicates if an item has been bookmarked to a list of favourites or similar. Use vf-button instead of this component for the main call to action on a page.

github location npm version

Usage

This component shows if a piece of content has been selected by a user as a favourite using a text label and icon.

No JavaScript functionality is provided and it is expected that the state handling will be done on a case-by-case basis on the project application.

Use vf-button instead of this component for the main call to action on a page.

Active state

The active state of the icon is managed by adding the class vf-bookmark--active. This class should be added by your framework or sever-side code.

Options

The component can be configured with a number of options.

  • bookmark_href: defaults to JavaScript:Void(0);
    • Any url that may be required.
  • label_inactive: defaults to Bookmark
  • label_active: defaults to Bookmarked
  • is_active: defaults to true
    • true or false
    • sets vf-bookmark--active CSS class
    • determines the appropriate label_inactive or label_active
  • modifier: defaults to inline
    • inline or button
  • icon: defaults to heart

Accessibility

This component targets WCAG 2.1 AA accessibility.

Note that the SVG icons use aria-hidden="true" as to be ignored by screen readers.

Pages that use this component

The EMBL-EBI Training site includes pages that use the inline variant to mark a training course as favourite and a customised version of the button variant to mark a page as complete.

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 = {
  "component-type": "element",
  "bookmark_href": "JavaScript:Void(0);",
  "label_inactive": "Add as bookmark",
  "label_active": "Bookmarked",
  "is_active": false,
  "modifier": "button",
  "icon": "heart"
}
 %}
{% include "../path_to/vf-bookmark/vf-bookmark.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-bookmark', {
  "component-type": "element",
  "bookmark_href": "JavaScript:Void(0);",
  "label_inactive": "Add as bookmark",
  "label_active": "Bookmarked",
  "is_active": false,
  "modifier": "button",
  "icon": "heart"
} %}
