## Features

- **iFrame block** — Registers an `iframe` block that allows editors to embed any external URL inside an `<iframe>` on a Volto page.
- **URL allowlist** — Supports a configurable `validUrls` list to restrict which URLs editors are permitted to embed, preventing misuse.

## Installation

To install your project, you must choose the method appropriate to your version of Volto.


### Volto 17 and earlier

Create a new Volto project (you can skip this step if you already have one):

```
npm install -g yo @plone/generator-volto
yo @plone/volto my-volto-project --addon @kitconcept/volto-iframe-block
cd my-volto-project
```

Add `@kitconcept/volto-iframe-block` to your package.json:

```JSON
"addons": [
    "@kitconcept/volto-iframe-block"
],

"dependencies": {
    "@kitconcept/volto-iframe-block": "*"
}
```

Download and install the new add-on by running:

```
yarn install
```

Start volto with:

```
yarn start
```

### Volto 18 and later

Add `@kitconcept/volto-iframe-block` to your `package.json`:

```json
"dependencies": {
    "@kitconcept/volto-iframe-block": "*"
}
```

Add `@kitconcept/volto-iframe-block` to your `volto.config.js`:

```javascript
const addons = ['@kitconcept/volto-iframe-block'];
```

If this package provides a Volto theme, and you want to activate it, then add the following to your `volto.config.js`:

```javascript
const theme = '@kitconcept/volto-iframe-block';
```

## Test installation

Visit http://localhost:3000/ in a browser, login, and check the awesome new features.

## Block configuration

`validUrls` allows you to restrict the use of the iFrame block by restricting the URLs that editors are allowed to embed in the `iframe`. If an unvalid URL is entered, an error is thrown.

```js
config.blocks.blocksConfig.iframe.validUrls = [''];
```

## Development

The development of this add-on is done in isolation using a new approach using pnpm workspaces and latest `mrs-developer` and other Volto core improvements.
For this reason, it only works with pnpm and Volto 18 (currently in alpha).
