# Presets
<blockquote className="caution">

__Alpha:__
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 `presets` property lets you define named visual variations of your component. Each key in the `presets` map is the preset's unique identifier, which is referred to as the preset key throughout this documentation. Each value configures the preset's display name, thumbnail, sizing, default values, and optional style overrides.

## Where to define

You can define `presets` in [`editorElement`](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/site-extensions/editor-react-components/manifest-reference/editor-element/editor-element.md).

<blockquote className="important">

**Important:** For presets to work, your component must wrap its root element in a container and spread `wix.presetsWrapperProps` onto it.

</blockquote>

## Preset defaults vs. style overrides

Each preset item has 2 fields that control its appearance: `presetDefaults` and `styleOverrides`. Both are optional, and they serve different purposes:

- Use `presetDefaults` to define the initial values that apply when a Wix user switches to a preset. This includes layout behavior, CSS properties, CSS custom properties, display filters, and nested element defaults. These values replace the component's base configuration for that preset.
- Use `styleOverrides` when you need breakpoint-aware or state-aware value overrides. For example, you might use `styleOverrides` to set a different hover color on mobile, or to adjust font sizes across breakpoints. Overrides in the `default` breakpoint cascade to all other breakpoints, while `small` overrides apply only to the mobile breakpoint.

## Preset item properties

Each item in the `presets` map accepts the following properties:

<PropertyList bordered>
  <Property
    name="displayName"
    type="string"
    description="The name shown in the editor's preset selector. Maximum 100 characters. Translatable."

## Installation presets

The `installation.presets` object maps breakpoints to preset keys, controlling which preset the component starts with when first added to the page.

<PropertyList bordered>
  <Property
    name="large"
    type="string"
    description="The preset key to use at the large (desktop) breakpoint."
  />
  <Property
    name="small"
    type="string"
    description="The preset key to use at the small (mobile) breakpoint."
  />
</PropertyList>

## Examples

### Basic presets

The following defines 2 presets for a line component, 1 horizontal and 1 vertical, each with different initial sizes and layout defaults.

```typescript
editorElement: {
  presets: {
    horizontal: {
      displayName: 'Horizontal',
      initialSize: {
        width: {
          sizingType: 'pixels',
          pixels: 280,
        },
        height: {
          sizingType: 'content',
        },
      },
      presetDefaults: {
        layout: {
          resizeDirection: 'horizontal',
          contentResizeDirection: 'vertical',
          disableStretching: false,
          disablePositioning: false,
        },
      },
    },
    vertical: {
      displayName: 'Vertical',
      initialSize: {
        width: {
          sizingType: 'content',
        },
        height: {
          sizingType: 'pixels',
          pixels: 280,
        },
      },
      presetDefaults: {
        layout: {
          resizeDirection: 'vertical',
          contentResizeDirection: 'horizontal',
          disableStretching: false,
          disablePositioning: false,
        },
      },
    },
  },
}
```

### Preset element defaults

The following configures layout, CSS property defaults, and display filters for a menu preset. The `displayFilters` object controls which elements, actions, and properties appear in the editor for this preset. In this case, it shows the `navbar` element and hides the `manageMenu` action.

```typescript
editorElement: {
  presets: {
    menuPreset: {
      presetDefaults: {
        layout: {
          resizeDirection: 'horizontal',
          contentResizeDirection: 'horizontal',
          disableStretching: false,
          disablePositioning: false,
          disableRotation: true,
        },
        cssProperties: {
          writingMode: {
            defaultValue: 'horizontal-tb',
          },
        },
        displayFilters: {
          elements: {
            show: ['navbar'],
          },
          actions: {
            hide: ['manageMenu'],
          },
        },
      },
    },
  },
}
```

### Inner element defaults

The following configures CSS custom property defaults for a nested `line` element.

```typescript
editorElement: {
  presets: {
    myPreset: {
      presetDefaults: {
        elements: {
          line: {
            cssCustomProperties: {
              type: {
                defaultValue: 'solid',
              },
              lineColor: {
                defaultValue: '#000000',
              },
              lineSize: {
                defaultValue: '1px',
              },
            },
          },
        },
      },
    },
  },
}
```

### Component initial size

The following sets the initial width to 120 pixels and the height to fit the content.

```typescript
editorElement: {
  presets: {
    myPreset: {
      initialSize: {
        width: {
          sizingType: 'pixels',
          pixels: 120,
        },
        height: {
          sizingType: 'content',
        },
      },
    },
  },
}
```

### Installation presets

The following sets the horizontal preset for both breakpoints and defines a default initial width of 280 pixels.

```typescript
installation: {
  presets: {
    default: 'horizontal',
    small: 'horizontal',
  },
  initialSize: {
    width: {
      sizingType: 'pixels',
      pixels: 280,
    },
    height: {
      sizingType: 'content',
    },
  },
}
```

### Style overrides

The following overrides background color with state-specific hover values at the default breakpoint, and adjusts font size for mobile.

```typescript
editorElement: {
  presets: {
    myPreset: {
      styleOverrides: {
        default: {
          style: {
            backgroundColor: {
              value: '#ffffff',
              statesValues: {
                hover: '#f0f0f0',
              },
            },
            fontSize: {
              value: '16px',
            },
          },
          elements: {
            menuItem: {
              style: {
                padding: {
                  value: '12px 16px',
                },
              },
