   * @example
   * 
   *  "id" {string} or id {HTMLElement}, refers to any HTML element of the current document, as an identifier (string) or as an HTMLElement type, to display within the control's drop-down panel
   *  exobj {object}, where exobj can be any of exontrol canvas-types as listed:
   * 
   *    {exontrol.Bezier}, The ExBezier/JS component displays Bézier curves. The Bézier curves are also used in the time domain, particularly in animation, user interface design and smoothing cursor trajectory in eye gaze controlled interfaces (requires "exontrol.bezier.js" library)
   *    {exontrol.Calendar}, The ExCalendar/JS component provides calendar capabilities for your application. A calendar is a system of organizing days for social, religious, commercial or administrative purposes. This is done by giving names to periods of time, typically days, weeks, months and years. A date is the designation of a single, specific day within such a system (requires "exontrol.calendar.js" library)
   *    {exontrol.Gantt}, The ExGantt/JS component is our approach to create timeline charts (also known as Gantt charts). Gantt chart is a time-phased graphic display of activity durations. Activities are listed with other tabular information on the left side with time intervals over the bars. Activity durations are shown in the form of horizontal bars (requires "exontrol.menu.js", "exontrol.tree.js", "exontrol.gantt.js" libraries)
   *    {exontrol.Gauge}, The ExGauge/JS library provides graphics capabilities to visually display and edit the amount, level, or contents of something. The view can show one or more layers, where each layer can display one or more transparent pictures, HTML captions which can be clipped, moved, rotated or combination of them, by dragging the mouse, rolling the mouse wheel, or using the keyboard (requires "exontrol.gauge.js" library)
   *    {exontrol.Menu}, The ExMenu/JS component provides menu-functionaly which includes top-level menus, context, popup, drop down or shortcut menus. A menu presents a list of items, commands, attributes, or states from which a user can choose. An item within a menu is known as a menu item, and may be configured to initiate an action, toggle a state on or off, or display a submenu of additional menu items when it is selected. A context menu is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation (requires "exontrol.menu.js" library)
   *    {exontrol.OrgChart}, The ExOrgChart/JS component permits the totally automatic generation of organigrams. An organigram generally provides a clear picture of the hierarchical position of the various actors. The control shows a hierarchical display of nodes, each one having an HTML caption, pictures and icons aligned to any side of the node. Each node can have child-nodes, assistant-nodes or group-nodes (requires "exontrol.orgchart.js" library)
   *    {exontrol.Pivot}, The ExPivot/JS is our approach to provide data summarization, as a pivot table. A pivot-table can automatically sort, count, total or give the average of the data stored in one table or spreadsheet (requires "exontrol.menu.js", "exontrol.tree.js", "exontrol.pivot.js" libraries)
   *    {exontrol.RadialMenu}, The ExRadialMenu/JS (radial or pie menu) component is similar to the Microsoft's OneNote radial menu with ability to customize the appearance and functionality. The component is designed using tree structure so an item can hold none or more children, and so any item can be browsed, and show its children around it (requires "exontrol.radialmenu.js" library)
   *    {exontrol.Schedule}, The ExSchedule/JS library is our approach to provide scheduling of appointments into your web application. The ExSchedule/JS is a visual HTML5 component that shows a timeline view for multiple activities (event calendar). The time is displayed on the vertical (Y) axis and the activities are automatically arranged over a single or multiple dates (requires "exontrol.menu.js", "exontrol.calendar.js", "exontrol.icalendar.js", "exontrol.schedule.js" libraries)
   *    {exontrol.ScrollBar}, The ExScollBar/JS components provides scroll-bar/slider/track functionality for your application. A vertical or horizontal bar commonly located on the far right or bottom of a window that allows you to move the window viewing area up, down, left, or right. A slider or track bar is a graphical control element with which a user may set a value by moving an indicator
   *    {exontrol.Surface}, The ExSurface/JS lets you organize your objects to a surface. You can use the tool to generate organigrams, diagrams, graphs, flowcharts and so on (requires "exontrol.surface.js" library)
   *    {exontrol.SwimLane}, The ExSwimlane/JS lets you draw swim lane diagrams. A swim lane (or swimlane diagram) is a visual element used in process flow diagrams, or flowcharts, that visually distinguishes job sharing and responsibilities for sub-processes of a business process. Swim lanes may be arranged either horizontally or vertically (requires "exontrol.surface.js", "exontrol.swimlane.js" libraries)
   *    {exontrol.Tree}, The ExTree/JS component allows you to display and edit hierarchical-data. Features include: Multiple-Columns, Multiple-Views, Drag and Drop, Group-By, Filter-Prompt, Conditional-Format, Total Fields, and much more (requires "exontrol.menu.js", "exontrol.tree.js" libraries)
