teaser

Basic Teaser A teaser is an interactive block element. Its main purpose is to display relevant content for a resource or external link before user interaction, for which the entire element is clickable. The Twig template is the recommended usage for Drupal. Important Notes: signifier and headline props are required for a basic teaser. When using the signifier prop, it will automatically crop an to the defined ratio (16:9 for vertical and responsive layout, 1:1 for horizontal layout). When using bolt-image as the signifier, please be sure that the source image file has the appropriate ratio, otherwise there will be undesired white space. The headline prop and its children props are required for use. To set an action for the teaser, set an href (for links) or type and proper attributes (for buttons) with the headline.link_attributes prop. Demo
Twig
{% set image %} // <img> or <bolt-image> goes here {% endset %} {% include '@bolt-components-teaser/teaser.twig' with { signifier: image, headline: { text: 'This is the teaser headline', link_attributes: { href: 'https://www.pega.com', } }, } only %}

teaser layout

Teaser Layout There are currently three layout options, vertical, horizontal, and responsive. The default option is vertical. Important Notes: Vertical or responsive teaser accepts 16:9 aspect ratio signifier. Any other aspect ratio will automatically be cropped to a 16:9 ratio. Horizontal teaser accepts 1:1 (square) aspect ratio signifier. Any other aspect ratio will automatically be cropped to a 1:1 ratio. Demo

If it is set to video, a play icon will appear with the signifier. Time: this represents either video duration (for video, eg. 1:20) or estimated reading time (for external link and PDF, eg. 10 min read). If a value is set, the value will appear with the signifier. Demo

teaser status and actions

Teaser Status and Actions The status prop can be used to display status information about a resource such as locked and view count. Like and share buttons can be generated via the actions prop. Important Notes: View count can be set via the status.views prop. It can be numbers or string (eg. 28k). Locked status can be set via the status.locked prop. If this is set, a lock icon will appear with the signifier. Pass a like button into the like prop. Example code snippet is shown below. Pass a share popover menu into the share prop. Boundary is required on the popover. Example code snippet is shown below. Demo
Twig
// Set up the like and share buttons {% set like %} {% set icon_heart %} {% include '@bolt-components-icon/icon.twig' with { name: 'heart-open', } only %} {% endset %} {% include '@bolt-elements-text-link/text-link.twig' with { content: 'Like', icon_before: icon_heart, reversed_underline: true, attributes: { type: 'button', class: 'js-bolt-like-button', // JS target for handling the like function. }, } only %} {% endset %} {% set share %} {% set share_menu %} {% include '@bolt-components-share/share.twig' with { display: 'menu', text: 'Share this content', sources: [ ... ], } only %} {% endset %} {% set share_popover_trigger %} {% set icon_share %} {% include '@bolt-components-icon/icon.twig' with { name: 'share', } only %} {% endset %} {% include '@bolt-elements-text-link/text-link.twig' with { content: 'Share', icon_before: icon_share, reversed_underline: true, attributes: { type: 'button' }, } only %} {% endset %} {% include '@bolt-components-popover/popover.twig' with { trigger: share_popover_trigger, content: share_menu, spacing: 'none', boundary: '.js-bolt-target-teaser', // JS target for containing the popover within the teaser. } only %} {% endset %} // Set up the component {% include '@bolt-components-teaser/teaser.twig' with { like: like, share: share, status: { views: '28k', locked: true, }, attributes: { class: 'js-bolt-target-teaser', }, ... } only %}

teaser text options

Teaser Text Options The teaser allows for a few different text options, including eyebrow_text, headline, subheadline, and description. Important Notes: When setting the headline and subheadline please be sure to set the proper HTML tag to ensure SEO and accessibility best practices. The traditional eyebrow/headline/subheadline lockup is best used in responsive layout. Demo
Twig
{% include '@bolt-components-teaser/teaser.twig' with { eyebrow_text: 'This is the eyebrow', headline: { text: 'This is the headline', tag: 'h2', size: 'xxlarge', link_attributes: { href: 'https://www.pega.com', } }, subheadline: { text: 'This is the subheadline', tag: 'h3', size: 'xlarge', }, description: { content: 'This is the description.', }, ... } only %}
