Svelte Accordion - Flowbite

Use the accordion component to show hidden information based on the collapse and expand state of the child elements using data attribute options

The accordion component is a collection of vertically collapsing header and body elements that can be used to show and hide information based on the Tailwind CSS utility classes and JavaScript from Flowbite.

A popular use case would be the “Frequently Asked Questions” section of a website or page when you can show questions and answers for each child element.

Setup #

  • Svelte
<script>
  import { AccordionItem, Accordion } from 'flowbite-svelte';
</script>

Default accordion #

Accordion uses the single selection mode by default i.e. it collapses every other child element when expanding a one.

To prevent that behavior set multiple property to true.

  • Svelte
<script>
  import { AccordionItem, Accordion } from 'flowbite-svelte';
</script>

<Accordion>
  <AccordionItem>
    <span slot="header">My Header 1</span>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
    <p class="text-gray-500 dark:text-gray-400">

      and start developing websites even faster with components on top of Tailwind CSS.
    </p>
  </AccordionItem>
  <AccordionItem>
    <span slot="header">My Header 2</span>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Learn more about these technologies:</p>
    <ul class="list-disc ps-5 dark:text-gray-400 text-gray-500">
      <li>
        <a href="/" target="_blank" rel="noreferrer" class="text-blue-600 dark:text-blue-500 hover:underline"> Lorem ipsum </a>
      </li>
      <li>
        <a href="https://tailwindui.com/" rel="noreferrer" target="_blank" class="text-blue-600 dark:text-blue-500 hover:underline"> Tailwind UI </a>
      </li>
    </ul>
  </AccordionItem>
</Accordion>

Always open #

Use the open prop to make an item open on mount.

  • Svelte
<script>
  import { AccordionItem, Accordion } from 'flowbite-svelte';
</script>

<Accordion>
  <AccordionItem open>
    <span slot="header">Header 2-1</span>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
  </AccordionItem>
  <AccordionItem>
    <span slot="header">Header 2-2</span>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
  </AccordionItem>
</Accordion>

Color option #

You can control the look and feel of AccordionItems by overwriting the activeClass and inactiveClass properties. You can define them in Accordion so that they will apply to all children or set them individually on each AccordionItem.

  • Svelte
<script>
  import { AccordionItem, Accordion } from 'flowbite-svelte';
</script>

<Accordion activeClass="bg-blue-100 dark:bg-gray-800 text-blue-600 dark:text-white focus:ring-4 focus:ring-blue-200 dark:focus:ring-blue-800" inactiveClasses="text-gray-500 dark:text-gray-400 hover:bg-blue-100 dark:hover:bg-gray-800">
  <AccordionItem class="">
    <span slot="header">Header 2-1</span>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
  </AccordionItem>
  <AccordionItem>
    <span slot="header">Header 2-2</span>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
  </AccordionItem>
</Accordion>

Flush accordion #

Use flush prop to remove the rounded borders.

  • Svelte
<script>
  import { AccordionItem, Accordion } from 'flowbite-svelte';
</script>

<Accordion flush>
  <AccordionItem>
    <span slot="header">Header 2-1</span>
    <p class="mb-2 text-gray-500 dark:text-gray-400">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Illo ab necessitatibus sint explicabo ...</p>
  </AccordionItem>
  <AccordionItem>
    <span slot="header">Header 2-2</span>
