PFElements Accordion Element

Usage

<pfe-accordion>
  <pfe-accordion-header>
    <h2>Why do wizards need money if they could just create it?</h2>
  </pfe-accordion-header>
  <pfe-accordion-panel>
    <p>There is legislation that decides what you can conjure and what you can not. Because things that you conjure out of thin air will not last, it is illegal in the wizarding world.</p>
  </pfe-accordion-panel>
  <pfe-accordion-header>
    <h2>Why doesn't Harry have a portrait of his parents?</h2>
  </pfe-accordion-header>
  <pfe-accordion-panel>
    <p>The characters in the portraits are not actually ghosts. They mainly are there just to repeat common phrases or serve as a general representation of the individual they depict. A portrait of his parents would not be of much help to Harry.</p>
  </pfe-accordion-panel>
</pfe-accordion>

Slots

Default slot in pfe-accordion

Place the pfe-accordion-header and pfe-accordion-panel elements here.

Default slot in pfe-accordion-header

We expect the light DOM of the pfe-accordion-header to be a heading level tag (h1, h2, h3, h4, h5, h6)

Default slot in pfe-accordion-panel

Add the content for your accordion panel here.

Attributes

context Changes the context of the accordion to one of 3 possible options:

• light (default)
• dark
• saturated

This will override any context being passed from a parent component and will add a style attribute setting the --context variable.

disclosure If pfe-accordion has one pfe-accordion-header, it will get tagged with disclosure="true". This applies a slightly different set of styles: chevron appears on the left side, the header has a single border on all four sides. Applying disclosure="false" to a pfe-accordion element containing only one header/panel pairing will set the element to display as a standard accordion.

Events

pfe-accordion:change

Fires when an pfe-accordion-header is activated. The detail object contains the following

detail: {
  expanded: Boolean
}

Test

npm run test

Build

npm run build

Demo

Code style

Accordion (and all PFElements) use Prettier to auto-format JS and JSON. The style rules get applied when you commit a change. If you choose to, you can integrate your editor with Prettier to have the style rules applied on every save.
