Usage

Basic usage

// Create the element
const element = session.createElement("treasury-breakdown-element", {
  onClose: (ev) => {
    console.log("Breakdown closed");
  },
});

// Mount it to a container
element.mount("#breakdown-container");

// Show the breakdown in a modal overlay
const modal = session.showTreasuryBreakdownModal({
  onClose: (ev) => {
    ev.preventDefault();
    modal.close();
  },
});

Listening to events

const element = session.createElement("treasury-breakdown-element", {});

element.on("ready", () => {
  console.log("Breakdown loaded");
});

element.on("close", (ev) => {
  console.log("User closed the breakdown");
});

element.mount("#container");

const element = session.createElement("treasury-breakdown-element", {

    console.log("Breakdown is ready");
  },
  onClose: (ev) => {

Methods

`mount(container)`

Mount the element to a DOM container. The container must be an empty element. The element will be appended as a child. If the element is already mounted, this method will log a warning and return.

Parameter	Type	Description
`container`	`HTMLElement` \| `#$\{`string`\}`	The container element or a CSS selector starting with ’#‘

// Using a selector
element.mount("#my-container");

// Using an element reference
const container = document.getElementById("my-container");
element.mount(container);

`unmount()`

Remove the element from the DOM and clean up all event listeners. After unmounting, the element instance should not be reused. Create a new element instance if you need to mount again.

// Unmount when done
element.unmount();

// Commonly used in event handlers
element.on("complete", () => {
  element.unmount();
});

`updateOptions(options)`

Update the element’s configuration options after creation. Only the provided options will be updated; other options remain unchanged. The element will re-render with the new options.

Parameter	Type	Description
`options`	`Partial`<`TreasuryBreakdownElementOptions`>	Partial options object with the values to update

// Update a single option
element.updateOptions({
  onComplete: (ev) => {
    console.log("New handler!");
  },
});

`getSnapshot()`

Get the current state snapshot of the element. The snapshot contains the element’s current internal state, such as loading status, form values, or other element-specific data. Returns: TreasuryBreakdownElementSnapshot

const snapshot = element.getSnapshot();
console.log("Current state:", snapshot.state);

// Or listen for changes
element.on("snapshot", (snapshot) => {
  console.log("State changed:", snapshot);
});
