 * });
 *
 * @param opts
 * @param {function(Object)} [opts.check] - Function to check whether item should show on the context menu, called with the target jquery element, shows if return is truthy
 * @param {string|function(Object)} opts.className - class name for the menu item, should be prefixed for non-default menu items (if function, called with jquery element, and uses return value)
 * @param {string|function(Object)} opts.data - data that will be sent to the callback function (if function, called with jquery element, and uses return value)
 * @param {string|function(Object)} opts.displayName - text to display on the menu item (if function, called with jquery element, and uses return value)
 * @param {function(Object)} opts.callback - Function to call when the context menu item is clicked, called with the data requested in opts.data
