Hi Ivan,

A few feedbacks about https://github.com/iberdinsky-skilld/ui_suite_material/tree/main/compone...

The attributes object is missing:

<md-list aria-label="Interactive example">

Proposal:

<md-list {{ attributes.setAttribute("aria-label", "Interactive example") }}>

Aria label must be a string prop instead of hardcoded value. Proposal:

<md-list {{ attributes.setAttribute("aria-label", aria_label) }}>

It is not necessary to define attributes because automatically injected.

items schema is not defined enough:

    items:
      type: array
      title: List items

Because it is a list of links, proposal:

items:
  type: object
    properties:
      title: { type: string }
      url:
        type: string
        format: iri-reference

If you target UI Patterns 2, there is an available shortcut:

"$ref": "ui-patterns://links"

Thank you for review. This was fast approach.
