Modal

Overview

Modals display information in a window or help a user focus on a task without navigating them away from the page. A user can’t perform other actions until the modal is dismissed.

Installation

npm install @patternfly/pfe-modal

Usage

With a trigger

The pfe-modal--trigger slot can be used with a trigger element, like a button, to provide a mechanism to open a modal without any additional JavaScript.

<pfe-modal>
  <button slot="pfe-modal--trigger">Open modal</button>
  <h2 slot="pfe-modal--header">Modal with a header</h2>
  <p>Lorem ipsum dolor sit amet, <a href="#foo">consectetur adipisicing</a> elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
  <pfe-cta>
    <a href="#bar">Learn more</a>
  </pfe-cta>
</pfe-modal>

Without a trigger

Using pfe-modal without utilizing the pfe-modal--trigger slot requires additional JavaScript to programmatically open a modal. Uses for this type of modal are meant for scenarios where a modal needs to be programmatically triggered: a user is being logged out, a user needs to accept terms before continuing, etc.

<pfe-modal>
  <h2 slot="pfe-modal--header">Modal with a header</h2>
  <p>Lorem ipsum dolor sit amet, <a href="#foo">consectetur adipisicing</a> elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
  <pfe-cta>
    <a href="#bar">Learn more</a>
  </pfe-cta>
</pfe-modal>

Slots

pfe-modal--trigger

The only part visible on page load, the trigger opens the modal window. The trigger can be a button, a cta or a link. While it is part of the modal web component, it does not contain any intrinsic styles.

pfe-modal--header

The header is an optional slot that appears at the top of the modal window. It should be a header tag (h2-h6).

default slot

The default slot can contain any type of content. When the header is not present this unnamed slot appear at the top of the modal window (to the left of the close button). Otherwise it will appear beneath the header.
