Installation

Resources are available within the CdrAccordion package;

• Component: @rei/cdr-accordion
• Component styles: cdr-accordion.css

To incorporate the required assets for a component, use the following steps:

#1. Install using NPM

Install the CdrAccordion package using npm in your terminal:

Terminal

    npm i -s @rei/cdr-accordion

#2. Import Dependencies

main.js

// import your required css
import "@rei/cdr-accordion/dist/cdr-accordion.css";

#3. Add component to a template

local.vue

<template>
  <cdr-accordion>
    <cdr-accordion-item
      id="default-example"
      label="This is the label text"
    >
      This is the accordion content.
    </cdr-accordion-item>
  </cdr-accordion>
</template>

<script>
  import { CdrAccordion, CdrAccordionItem } from "@rei/cdr-accordion";

  export default {
    ...
    components: {
      CdrAccordion,
      CdrAccordionItem
    }
  }
</script>

Usage

Style

Use cdr-accordion to pass styling options to cdr-accordion-item.

<template>
  <cdr-accordion
    :compact="true"
  >
    <cdr-accordion-item
      id="item-1"
      label="Label text"
    >
      Accordion content here
    </cdr-accordion-item>
  </cdr-accordion>
</template>

Behavior

Set show-all to true on cdr-accordion, and each cdr-accordion-item will display in an open state.

<template>
  <cdr-accordion
    :show-all="true"
  >
    <cdr-accordion-item
      id="item-1"
      label="Label text"
    >
      Accordion content here
    ...

The CdrAccordionItem component can also be controlled individually. If show-all is false at the CdrAccordion level, set show to true to display an individual accordion item in an open state. Note that CdrAccordion settings will take precedence over CdrAccordionItem settings.

<template>
  <cdr-accordion>
    <cdr-accordion-item
      id="item-1"
      label="Label text"
      :show="true"
    >
      Accordion content here
    ...

Any options set at the cdr-accordion level can be set on any parent component of cdr-accordion-item by using Vue's provide/inject functionality. This is useful, for instance, if cdr-accordion-item ever needs to be used as a part of another group component.

<template>
  ...
  <cdr-accordion-item
    id="item-1"
    label="Label text"
  >
    Accordion content here
  </cdr-accordion-item>
  ...
</template>

<script>
  export default {
    ...
    provide() {
      return {
        borderAligned: true,
        showAll: true
      };
    }
  }
</script>
