Data Sources

The library supports three main data sources:

• Single JSON file. In this case, all data is placed within a single JSON file, which is loaded once on page load.
• Javascript object. This data source is the simplest one. Just create a JavaScript object and pass it to the library via the dataSource property.
• Custom function. The custom function allows to apply any logic and, for example, bring data from the server-side (via AJAX requests).

Storage & Deep Links

The library supports storage to save the current state and restore it after page refresh or when the back button is pressed.

• Local storage – this is persistent storage that keeps data even if the user closes the browser.
• Session storage – it will be cleared when the browser session is over, typically when the user closes the browser.
• Cookies – unlike local and session storage, cookie values can be used on the server too. It’s also possible to define cookies’ expiration date.
• Deep Links – special links that send users directly into the predefined drop-down selection state.

Callbacks & APIs

Th library has various callback function that may be used to apply the custom logic:

• onSubmit.
• onReset.
• onChangeStart.
• onChangeEnd.
• onDisableControl.
• onEnableControl.
