Documentation + Live Demo ↗

<vaadin-virtual-list></vaadin-virtual-list>

<script>
  const list = document.querySelector('vaadin-virtual-list');
  list.items = items; // An array of data items
  list.renderer = (root, list, { item, index }) => {
    root.textContent = `#${index}: ${item.name}`;
  };
</script>

Installation

Install the component:

npm i @vaadin/virtual-list

Once installed, import the component in your application:

import '@vaadin/virtual-list';

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/virtual-list/theme/material/vaadin-virtual-list.js';

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

import '@vaadin/virtual-list/theme/lumo/vaadin-virtual-list.js';

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

import '@vaadin/virtual-list/src/vaadin-virtual-list.js';
