Component outputs

Receive every typed component output

Use declarative output handlers in .wrn files or register a direct output handler from JavaScript. The canonical API exposes payload and does not require event.detail.

@selectFires when an item, option, card, or result is selected.
@toggleFires when the component changes between open and closed or on and off states.
@expandFires when the component emits the expand event.
@collapseFires when the component emits the collapse event.
Declarative handlers.wrn
<TreeView
  @select='console.log(payload)'
  @toggle='console.log(payload)'
  @expand='console.log(payload)'
  @collapse='console.log(payload)'
/>
Direct output handlers.js
import { registerOutputHandler } from "@wrnexus/csr/outputs"

const component = document.querySelector("[data-ui-component=\"TreeView\"], [data-component=\"TreeView\"]")

if (component) registerOutputHandler(component, "select", (payload) => {
  console.log("select", payload)
})

if (component) registerOutputHandler(component, "toggle", (payload) => {
