Rich options

Radio and checkbox groups can say more about each option (like a list of providers to pick from). Besides label, value and group, an option can have:

Property
badge	a short tag after the label, e.g. "Most used"
description	a second line of smaller text under the label
image	a logo (at most 28 px high, keeps its proportions). Where it goes is set per question with config.imagePosition: left (default: before the label, on its line; it wraps only when the line is full), right (right after the label, before its badge and help), top or bottom (on a line of its own, above the label or under the description and link). Only http(s), relative and data:image/…;base64 addresses are used. imageAlt describes it for screen readers (empty by default: the label already names it)
link	{ label, url }: a link after the description that opens in a new tab (rel="noopener noreferrer"). Only http(s) URLs; clicking it does not pick the option
help	a text behind a small "?" after the label (hover, focus, click or tap; Escape closes it). Clicking the "?" does not pick the option

{
  "type": "radioGroup", "id": "deposit", "model": "deposit", "label": "Who holds the deposit?",
  "config": { "optionStyle": "cards", "visibleOptions": 3 },
  "options": [
    { "label": "Bank guarantee", "value": "bank", "badge": "Most used", "image": "https://example.com/bank.svg",
      "description": "The bank pays if something goes wrong.", "link": { "label": "Read more", "url": "https://example.com/bank" },
      "help": "You pay a small yearly fee instead of the full deposit." }
  ]
}

With config.optionStyle: "cards", options that use any of these get the provider-list look: bordered cards on a light background, the radio / tick on the left and the content on the right, the picked card outlined in the primary colour. Cards without them keep the big tile look. All texts are translatable (field.<id>.optionBadge.<value>, optionDesc, optionHelp, optionLink, optionAlt), and so is a field's tooltip (field.<id>.tooltip).
