Free and Open Source Web Builder Framework

/**
 * With Style Manager you build categories (called sectors) of CSS properties which could be used to customize the style of components.
 * You can customize the initial state of the module from the editor initialization, by passing the following [Configuration Object](https://github.com/GrapesJS/grapesjs/blob/master/src/style_manager/config/config.ts)
 * ```js
 * const editor = grapesjs.init({
 *  styleManager: {
 *    // options
 *  }
 * })
 * ```
 *
 * Once the editor is instantiated you can use its API and listen to its events. Before using these methods, you should get the module from the instance.
 *
 * ```js
 * // Listen to events
 * editor.on('style:sector:add', (sector) => { ... });
 *
 * // Use the API
 * const styleManager = editor.StyleManager;
 * styleManager.addSector(...);
 * ```
 * ## Available Events
 * * `style:sector:add` - Sector added. The [Sector] is passed as an argument to the callback.
 * * `style:sector:remove` - Sector removed. The [Sector] is passed as an argument to the callback.
 * * `style:sector:update` - Sector updated. The [Sector] and the object containing changes are passed as arguments to the callback.
 * * `style:property:add` - Property added. The [Property] is passed as an argument to the callback.
 * * `style:property:remove` - Property removed. The [Property] is passed as an argument to the callback.
 * * `style:property:update` - Property updated. The [Property] and the object containing changes are passed as arguments to the callback.
 * * `style:target` - Target selection changed. The target (or `null` in case the target is deselected) is passed as an argument to the callback.
 * <!--
 * * `styleManager:update:target` - The target (Component or CSSRule) is changed
 * * `styleManager:change` - Triggered on style property change from new selected component, the view of the property is passed as an argument to the callback
 * * `styleManager:change:{propertyName}` - As above but for a specific style property
 * -->
