The schema property

Each brick should have a schema static property, which has the following TypeScript interface:


interface IBlockType<T = Props> {
name: string
label: string
getDefaultProps?: () => Partial<T>
hideFromAddMenu?: boolean
sideEditProps?: Array<ISideEditProp | ISideGroup>
repeaterItems?: IRepeaterItem[]
newItemMenuOpen?: boolean
groupByRepeater?: boolean
mapExternalDataToProps?: (externalData: Props, brickProps?: T) => Partial<T>
playgroundLinkUrl?: string
playgroundLinkLabel?: string
theme?: string
category?: string
tags?: string[]
previewImageUrl?: string
previewIcon?: React.ReactElement
stories?: BrickStory<T>[]

The ISideEditProp / ISideGroup interface is explained in the Side edit props page.
The Repeater interface is explained in the Repeater page.

Properties definition

nameThe unique name for this block type (for example "hero-unit"). "RB_PAGE_EMBED is a reserved word and should be used only for a "page/entity embed" brick.
labelThe name displayed in the Sidebar when you want to add a new block (for example "Hero Unit").
getDefaultPropsA function returning the default props for new added blocks.
hideFromAddMenuIf true, the component isn't shown in the list of components available in the "add block" menu. For example, you may want to hide a block that can be used only inside of a <Repeater />.
sideEditPropsThe array of objects representing the props the user will be able to modify in the right Sidebar, with their display properties. See Side Edit Props.
repeaterItemsArray to specify behaviour of the bricks used in the <Repeater> components. See Repeater.
newItemMenuOpenIf true the "Add new..." accordion menu is open by default; if false it is closed by default; otherwise, by default it is open when the number of repeaterItems is less than or equal to 4 and closed otherwise.
groupByRepeaterfalse by default. If set to true the items that can be repeated are grouped by repeater (if you set the positionLabel the title of each collapsible section is the positionLabel).
mapExternalDataToPropsFunction that gets as first argument the external data (from the getExternalData function specified on the pageType) and as second argument the props on this brick. It should return the new props for this brick. See External content.
playgroundLinkUrlUrl to link in the Playground, for example to link docs, guidelines, etc.
playgroundLinkLabelText for the link in the Playground, for example to link docs, guidelines, etc.
categoryUsed to categorize bricks. Bricks will be shown grouped by category.
tagsTags are used to search bricks in the Admin interface.
previewImageUrlImage URL to be used as preview image for this brick. You can create easily a "screenshot image" of a brick from the Playground. It is shown only if you set the enablePreviewImage flag to true in the React Bricks configuration.
storiesYou may define default stories on a brick. Editors will be able to add their own stories saved on the React Bricks APIs. This feature is available only for "Pro" and upper plans. See Stories and the BrickStory type

Usage example

HeroUnit.schema = {
name: 'hero-unit',
label: 'Hero Unit',
category: 'headings', // to organize bricks by category
tags: ['hero', 'jumbotron', 'heading'],
// Defaults when a new brick is added
getDefaultProps: () => ({
background: { color: '#fff', className: 'bg-white' },
title: 'Thick as a React Brick',
// Sidebar Edit props
sideEditProps: [
name: 'background',
label: 'Background',
type: types.SideEditPropType.Select,
selectOptions: {
display: types.OptionsDisplay.Color,
options: [
// The color is the unique mandatory property for a select with display "color"
{ value: { color: '#fff', className: 'bg-white' }, label: 'White' },
value: { color: '#f3f4f6', className: 'bg-gray-100' },
label: 'Gray',
