Jeegoocontext is a jQuery plugin that allows for multiple custom context menus (pop-up menus) to exist on a single page. The plugin is able to transform any unordered list appended to the body into a multi-level, intelligently positioned styled context menu via a single call.

Features:

* Easy to implement.
* Both vertical and horizontal intelligent positioning.
* Customizable time delays to provide easy selection of items.
* Multiple context menus on a single page.
* Fully css customizable UI.
* Customizable behavior via callbacks.
* Customizable class names to avoid potential naming conflicts.
* Opera compatible.
* Cross-browser support
* Lightweight.
* Unobtrusive.

Easy to implement

Steps required to implement the plugin:

1. Include references to the jquery library, and to jquery.jeegoocontext.min.js.
2. Select a skin (skins cm_default and cm_blue included in the code-download) and include a reference to the skin’s stylesheet.
3. Append an unordered list to the body and give it a unique id and the following class name: “jeegoocontext” and the class name for the skin: “cm_default” or “cm_blue” for example.
4. Bind any context to the menu with the following call: $(‘context’).jeegoocontext(‘menu id’); Where ‘context’ can be any jQuery selector and ‘menu id’ contains the unique id of the menu, for example: $(‘.context’).jeegoocontext(‘menu_1′);

Both vertical and horizontal intelligent positioning

Normally the context menu opens exactly at the clicked position. However, when opened at the near edges of a webpage, the menu and subsequent submenus are offset to the left/top to avoid overflow to the right/bottom.

Overflow behavior can be customized by adjusting the widthOverflowOffset and heightOverflowOffset properties on the options object.

Customizable time delays to provide easy selection of items

The delay property on the options object provides time-out values to the menu to allow for easy selection of submenu items. Without these delays expanded submenus collapse immediately after a user moves his/her mouse to another list-item, which can be very annoying. The following animations illustrate these conditions:

Multiple context menus on a single page

Each page can contain multiple context menus. All that is required is that each menu contains a unique id and they all share the “jeegoocontext” class (overridable via the options.menuClass property).

Fully css customizable UI

The plugin contains very little presentation script, so the UI can be fully styled via css. The code-download includes a skins folder containing two skins named: “cm_default” and “cm_blue”. These skins consist of nothing more than an images folder and a stylesheet.
Customizable behavior via callbacks

The plugin publishes the following four useful events to provide customizable behavior:

1. onShow
2. onHover
3. onSelect
4. onHide

From within each of these callbacks default behavior can be cancelled by returning false.

Customizable class names to avoid potential naming conflicts

The plugin uses the following class names:

1. active
2. hover
3. jeegoocontext
4. submenu

All class names are overridable to avoid potential naming conflicts.

Opera compatible

Opera doesn’t allow right-click event overrides. When the plugin detects Opera it automatically binds the menu to the doubleclick event. The event-type can be overriden via the operaEvent property on the options object.

Cross-browser support

The plugin was tested in the following browsers: Opera 10, Safari 4, Chrome 3, Firefox 3, Internet Explorer 6, 7 & 8. Although compatible with all these browsers, it is not recommended to use the styled skin in IE 6 due to some (possible) weird caching bug. For some reasen IE 6 decides to re-download all images used in the menu on every mouseover.

Lightweight

The minified version of the script is just under 4 kb in size.

Unobtrusive

No changes to the page html are required except for appending the context menu to the body.
