# Installation

Editor React Components are currently in alpha. This feature is subject to change and may have bugs, issues, and limitations. We're actively improving it based on your feedback.

The `installation` property controls how your component appears when a Wix user first adds it to a page, including its initial dimensions, which preset it starts with, and where it's placed. It works together with [`layout`](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/layout.md): `installation` sets the starting size, and `layout` controls how the Wix user can resize from there.

## Where to define

You can only define `installation` at the root level of your manifest, alongside properties like `type` and `editorElement`. See the [manifest structure](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/root-properties/root-properties.md).

## Installation properties

The `installation` object supports the following properties:

<PropertyList bordered>

## Initial size

The `initialSize` property controls the starting dimensions when a Wix user first adds your component to a page. Each dimension (`width` and `height`) is configured independently with a sizing type.

## Examples

### Fixed width with content-driven height

The component has a set width but grows vertically to fit its content. This is the most common pattern, used by text components, accordions, and tabs.

```typescript
installation: {
  initialSize: {
    width: {
      sizingType: 'pixels',
      pixels: 400,
    },
    height: {
      sizingType: 'content',
    },
  },
}
```

### Full-width with content-driven height

The component stretches to fill its parent section while the height adjusts to content. Useful for banners, marquees, and full-width layouts.

```typescript
installation: {
  initialSize: {
    width: {
      sizingType: 'stretched',
    },
    height: {
      sizingType: 'content',
    },
  },
}
```

### Fully content-driven

Both dimensions adjust to the component's content. This works for components with an intrinsic size, like icon bars or badges.

```typescript
installation: {
  initialSize: {
    width: {
      sizingType: 'content',
    },
    height: {
      sizingType: 'content',
    },
  },
}
```

### Fixed dimensions with aspect ratio lock

The component maintains its width-to-height ratio when the user resizes it. Use `preserveAspectRatio` only when both dimensions use `'pixels'` sizing. Primarily useful for media components like images, videos, and logos.

```typescript
installation: {
  initialSize: {
    width: {
      sizingType: 'pixels',
      pixels: 320,
    },
    height: {
      sizingType: 'pixels',
      pixels: 240,
    },
    preserveAspectRatio: true,
  },
}
```

### Different presets for desktop and mobile

```typescript
{
  installation: {
    initialSize: {
      width: { sizingType: 'pixels', pixels: 320 },
      height: { sizingType: 'pixels', pixels: 240 },
    },
    presets: {
      large: 'desktopCard',
      small: 'mobileCard',
    },
  },

  editorElement: {
    presets: {
      desktopCard: {
        displayName: 'Desktop Layout',
        presetCssUrl: './presets/desktop.css',
        initialSize: {
          width: { sizingType: 'pixels', pixels: 600 },
          height: { sizingType: 'pixels', pixels: 400 },
        },
      },
      mobileCard: {
        displayName: 'Mobile Layout',
        presetCssUrl: './presets/mobile.css',
        initialSize: {
          width: { sizingType: 'pixels', pixels: 300 },
          height: { sizingType: 'pixels', pixels: 200 },
        },
      },
    },
  },
}
```
