Element Proposer
An Element Proposer is a component role within the [session][doc-session] describing a component that requests [elements][doc-element] to be added to the session through the [fuchsia.element.Manager][sdk-element-manager] API.
Element Proposers are components {#proposers-are-components}
Element Proposers are [components][doc-component] within a [session][doc-session]. They are distinct from other components within the same session by their role:
Element Proposers use the [fuchsia.element.Manager][sdk-element-manager] protocol to add [elements][doc-element] to the session.
Element Proposers drive product UI {#proposers-drive-product-ui}
Element Proposers can react to environmental inputs, including the following:
- Accepting direct keyboard input from the user
- Listening to requests from a mobile device on the same network
- Using predictive algorithms based on past user behavior
They then respond to these inputs by adding elements to the session.
A fully featured product contains multiple Element Proposers.
Element Proposers are portable across products {#proposers-are-portable}
Like the elements they propose, Element Proposers are reusable across products and product configurations. Including an Element Proposer is accomplished by including it in the [component topology][doc-component-topology] for the session.
