Variants

General

Variants are components that are grouped and share a set of properties. In this document they are referred simply as components. The group itself is called a VariantComponent.

A VariantComponent must contain at least one component.

Components

  • Each component has a variant-id attribute. All components in the same VariantComponent share the same variant-id.
  • Each component has a variant-properties attribute, which consists on a list/map of properties. For example: [{ name: "Property 1", value: "Value 1" } { name: "Property 2", value: "Value 2" }].
    • All components within a VariantComponent must have the same number of properties, with identical keys and in the same order.
    • The values can be the same or different across components.

Main shapes of components

Variant container

All main shapes for components of the same VariantComponent must be direct children of a variant container. A variant container is a frame with the following characteristics:

  • Its id equals the shared variant-id of its child components.
  • It has an attribute is-variant-container set to true.
  • A variant container without children is invalid. It must have at least one child.
  • The first child of the variant container is used to represent visually the entire VariantComponent in different places on Penpot, so the order of the children is significant.
  • When created in the interface of Penpot, it may include some attributes (e.g., flex layout, stroke color #bb97d8, border radius 20). These attributes are not mandatory. (TBD: Will the SDK create those attributes by itself?).

Main shape

The main shape of a component that belongs to a VariantComponent includes some extra attributes:

  • variant-id: same value as its component's variant-id and the variant container's id.
  • variant-name: a string composed by taking the values of the variant-properties of its component, removing the empty ones, and joining the remaining with ", ". Example: [{ name: 'Property 1', value: 'Value 1' } { name: 'Property 2', value: '' } { name: 'Property 3', value: 'Value 3' }] becomes Value 1, Value 3.

Copies of the components

Copies of components within a VariantComponent do not have any special attributes and behave like ordinary copies.
