Local Storage

Overview

This module provides local storage caching of user's data that is entered into form elements, preventing its loss after accidental page refresh or its closing.

There are two possible states for fields that use local storage caching:

• default value: default value of a field, the one that really is saved in the database
• restored value: value restored from local storage

The module plugins to control local storage caching - one can toggle form element value between restored or default state.
