Togle is a simple user-interface component that can make a huge impact on the overall user experience. Togle controls are used when the state of a toggle switch must be updated quickly, often without requiring the user to click a button or enter any data.

Toggle switches are an ideal control when users need to change the state of their preferences, settings or other types of information. They are easy to use, provide direct labels, and deliver immediate results.

Good Labels

Toggles can be confusing if they are not clearly labeled and it is essential to label each toggle correctly. The label should describe what state the toggle will be in, and what option it will be controlling.

Color is also an important indicator of toggle state. It is recommended to use a high-contrast color to signal that the toggle is on or off, as low-contrast colors can be hard for users to identify when the toggle is on.

Testing is a Key Part of Toggle Development

When you are implementing toggles it is vital to test them in their live state so that the toggle isn’t causing unexpected regressions when released to production. This means that you should test the toggle configuration you expect to become live in production (including any toggles you intend to release flipped On) and the fall-back configuration where those toggles are flipped Off.

The ability to re-configure feature flags dynamically via code at runtime is a powerful tool, but only where it is used with caution. In most cases it is preferable to use static toggle configuration stored in a database or some other centralized store.
