Attributes and Properties #

Property Attribute Type Default Description focusableSelector focusableSelector string gap gap `${'0' | `${number}px`}` '0' itemSize itemSize { width: number; height: number; } { width: 200, height: 200, } items items Record<string, unknown>[] [] padding padding `${'0' | `${number}px`}` | undefined selected selected Record<string, unknown>[] []

Events #

Name Type Description change Event Announces that the value of `selected` has changed

Description #

An <sp-grid> element displays a virtualized grid of elements built from its items, a normalized array of javascript objects, applied to a supplied renderItem, a TemplateResult returning method. sp-grid is a class extension of lit-virtualizer and as such surfaces all of its underlying methods and events.

Elements displayed in the grid can be focused via the roving tabindex that allows the grid to be entered via the Tab key and then subsequent elements to be focused via the arrow keys. To inform the <sp-grid> element what part of the DOM created by the renderItem method can be focused, supply a value to focusableSelector. Focus will always enter the element list at index 0 of ALL available elements, not just those currently realized to the page.

Elements rendered via renderItem can have their width and height customized by supplying a value for itemSize that accepts an object: { width: number, height: number }. You can customize the space between these elements via the gap property that accepts a value of 0 or ${number}px.

Usage #

See it on NPM! How big is this package in your project?

yarn add @spectrum-web-components/grid

Import the side effectful registration of <sp-grid> via:

import '@spectrum-web-components/grid/sp-grid.js';

When looking to leverage the Grid base class as a type and/or for extension purposes, do so via:

import { Grid } from '@spectrum-web-components/grid';
