Installation

Install the component:

npm i @vaadin/accordion

Once installed, import the component in your application:

import '@vaadin/accordion';

Themes

Vaadin components come with two built-in themes, Lumo and Material. The main entrypoint of the package uses the Lumo theme.

To use the Material theme, import the component from the theme/material folder:

import '@vaadin/accordion/theme/material/vaadin-accordion.js';

You can also import the Lumo version of the component explicitly:

import '@vaadin/accordion/theme/lumo/vaadin-accordion.js';

Finally, you can import the un-themed component from the src folder to get a minimal starting point:

import '@vaadin/accordion/src/vaadin-accordion.js';
