Getting started

Themes are sandboxed Liquid — data-only templates rendered server-side against a fixed data contract. Themes ship zero JavaScript: cart, item options and checkout come from the platform commerce runtime, which your markup binds to declaratively.

Download the starter theme (.zip)

1. Download and unzip the starter.
2. Rename the slug in theme.json.
3. Edit sections in sections/; add snippets in snippets/.
4. Zip the folder contents and submit it for review.

theme.json Manifest

{
  "name": "My Theme",
  "slug": "my-theme",          // letters/numbers/dashes — becomes the install path
  "version": "1.0.0",          // published versions are immutable; ship updates as new versions
  "author": "You",
  "description": "…",
  "min_platform_version": "2.0"
}

Templates & sections (OS 2.0)

templates/index.json lists section instances; each section is a Liquid file in sections/ carrying its settings schema in a schema block. Limits: ≤ 25 sections per template, ≤ 50 blocks per section.

// templates/index.json
{
  "sections": {
    "hero":  { "type": "hero", "settings": { "heading": "Welcome" } },
    "menu":  { "type": "menu-grid",
               "blocks": { "b1": { "type": "badge", "settings": { "label": "New" } } },
               "block_order": ["b1"] }
  },
  "order": ["hero", "menu"]
}

Inside a section file you receive section.id, section.type, section.settings.* and section.blocks (each block: id / type / settings.*). Setting types: text, textarea, color, checkbox, select (Options), range (min/max), image_picker.

Data — the Drop reference

Templates can reach only the properties below (generated from the platform's Drop classes — this table cannot drift). Globals: restaurant, options, settings, menu, allergies, banners, branches, active_branch, table, customer, localization, flags, stats, and section inside section files. Anything else renders blank (and errors at upload).

Filters & tags

Platform filters (plus the standard safe Liquid set — escape, date, where, map, sort, size…):

media_urlmoneymoney_codestudio_blockstudio_textttheme_asset

• t — translate a key. Read-only; unknown keys return the key itself.
• money / money_code — format a price with the business's currency.
• media_url — business image URL: {{ item.image | media_url: 'menu' }} (types: menu, logo, cover, allergy, banner).
• theme_asset — URL of one of your bundled assets: {{ 'css/style.css' | theme_asset }}.

Tags schema (section settings, stripped from output), render (snippets by name — your snippets/ dir only), commerce (emits the commerce runtime once per page). Unknown filters/tags fail at upload.

Commerce runtime

Drop {% commerce %} once (usually at the end of your template), then bind with data attributes — the runtime owns cart state, the option sheet and checkout:

<button data-mb-add="{{ item.id }}">Add</button>
<span   data-mb-cart-count></span>
<span   data-mb-cart-total></span>
<button data-mb-open-cart>Cart</button>
<button data-mb-call-waiter>Call waiter</button>
<div    data-mb-item-sheet-mount hidden></div>
<div    data-mb-cart-mount hidden></div>

Skin the runtime UI via its .mb-* classes and CSS custom properties (--mb-sheet-bg, --mb-sheet-ink, --mb-accent).

Merchant settings

Merchants customize your theme in the dashboard against your schemas. Precedence: schema defaults ← template values ← merchant values. Settings are stored independently of the theme version, so shipping an update never wipes a merchant's customization.

Rules & limits

• No <script>, no inline event handlers, no javascript: URLs, no iframes — rejected at upload.
• Escape user-visible data: {{ item.name | escape }}.
• Renders are resource-bounded (output length + engine work caps). A section that fails at runtime is skipped, never a blank page; at upload it is a hard error.
• Published versions are immutable — updates are new versions through review.
• Use logical CSS properties (inline-size, margin-inline…) — menus render RTL too.
