An internal utility component that provides show/hide functionality.

This component is intended only for internal Helios use. If you need to use it, please contact the Design Systems Team.

How to use this component

The MenuPrimitive component renders an interactive element that triggers a custom event handler provided by the :toggle block (passed via hash by Ember). To comply with accessibility best practices, this element is usually a button or a component that renders a button.

When the content is disclosed, the container can be closed in various way; toggling via the button (click or enter/return), clicking outside of the content, or via the esc key.

Note: DisclosurePrimitive, another variant of this primitive, excludes the functionality to close the content panel by either clicking outside of the content, or via the esc key.

  <:toggle as |t|>
    <button type="button" {{on "click" t.onClickToggle}}>Click me</button>

Content positioning

The :content block is not positioned in relation to the :toggle block. We recommend applying position: absolute to a wrapper around the content that is then passed to the :content block.
