/**
 * @whatItDoes
 *
 * This component creates sections in the page.
 * Each section can be expanded/collapsed to show its contents.
 * It also supports for auto loading while scrolling: it loads only the last visible
 * section header (from the bottom), where the scroll stops.
 *
 * By default, it reads all the sections inside and shows a quick jump menu in the right.
 * Also, the load on scroll is disable.
 *
 * For more options, see PageSection component.
 *
 * @howToUse
 *
 * ### Inputs
 * `PageSection[]` : **scrollSections** - List of PageSections to be used in the quick-jump menu. This overrides the list
 * `boolean` : **hideMargin** - Hides the margin
 * `boolean` : **loadOnScroll** - Loads a new section automatically when the user scrolls into it
 *
 * ### Example
 * This component can be used by the following example:
 *
 * ```HTML
 * <cmf-core-controls-page-sections>
 *
 *   <cmf-core-controls-page-section section-id="section1" name="Section 1 title">
 *      <div>Some content for section 1</div>
 *   </cmf-core-controls-page-section>
 *
 *   <cmf-core-controls-page-section section-id="section2" name="Section 2 title" *cmf-core-controls-defer-instantiation>
 *      <div>This content will only be displayed when the section is active or loaded</div>
 *   </cmf-core-controls-page-section>
 *
 * </cmf-core-controls-page-sections>
 * ```
