Options
The second argument to the creator function is the options argument. This is a JavaScript object containing name/value pairs: The name is the name of the option and the value is the desired setting. Components define their own default values for options, but integrators can override these defaults by providing new values using the options argument. For technical information about how options are merged with defaults, see Options Merging.

Selectors
One of the options that can be provided to the component is a set of CSS-based selectors identifying where in the DOM different elements can be found. The value for the option is itself a Javascript object containing name/value pairs:
selectors: { selector1Name: "selector 1 string", selector2Name: "selector 2 string", ... }
The component defines defaults for these selectors: If you use those defaults in your markup, you do not need to specify the selectors option. If you do choose to override any of the selectors, you can specify your custom selector using this option.
