IMAGELIST

Several IMAGE widgets laid out side by side, each taking an equal share of the row's width.

{
  "type": "IMAGELIST",
  "params": {
    "list": [
      { "url": "https://.../a.jpg", "type": "category", "id": 1 },
      { "url": "https://.../b.jpg", "type": "category", "id": 2 }
    ]
  }
}

Each entry in list uses the same fields as IMAGE (url, type, id, radius, padding, height_percent, ...) — each entry is an independent IMAGE, just laid out in an equal-width column instead of full row width. Entries with different height_percent values will end up different heights within the same row.
