Embed and render Form.io forms in any web app with the `@formio/js` renderer — by URL or JSON, pre-filled, controlled from JavaScript — and own field behavior: conditionals, calculated values, JSON Logic validation, cascading selects. The default "embed a form" entry point. Use when the user asks to "embed a form", "render a form", "add this form to my page", "pre-fill a form", "show or hide a field based on another field", "calculate a field value", "add custom validation to a field", or add…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Embedding Form.io Forms (Vanilla JS renderer)

Task guide for putting a Form.io form on a page and wiring its behavior with the `@formio/js` renderer. Everything routes through one API:

```js
const form = await Formio.createForm(element, srcOrJson, options);
```

## Preflight — the Form.io MCP server

**Check this when you reach your first Form.io tool call, not when this skill activates.** The check is whether `form_list` is callable by you, under whatever name this client exposes it. If it is, proceed. If it is not, load the `formio-mcp-setup` skill and use it to help the user connect the server; that skill is the only remedy you offer, and this skill writes no MCP configuration itself.

**A missing server blocks that call, not the turn.** Reading this skill, answering a question from it, planning, and writing files to the working directory all need no server. Do everything that needs no server first and in full, then raise the gap when you actually reach the call that needs it. Opening with a blocked-on-setup message — or asking for a Project URL before there is anything to write to it — spends the user's turn on a step that was not due.

How to install

The exact contents, by fingerprint

mdr add formio/ai/formio-form@sha256:384b3e7dd88b685d

The line at the top of this page pins the label git:20261030.a714871, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
