Togle is a simple user-interface component that makes it easy to update preferences, settings, and other information. It provides direct labels, standard visual design, and delivers immediate results.

Toggle Labels are clear and precise, with short words that describe what the control does when it’s on. Use a high-contrast color for the on state to signal the change and make sure state descriptors (such as “on” or “off”) are visible next to the toggle switch.

Good toggles should be consistent with other aspects of your product or site’s aesthetic and functionality. Avoid ambiguous labels and choose colors that are appropriate for your audience.

A good toggle will always have a default state, either “on” or “off.” This allows you to set the toggle switch to a single state without having to create a custom state for every use case. It also gives you more screen estate and flexibility to customize the appearance of the toggle to fit the rest of your interface and application.

Consider runtime configuration for feature flags and toggles

If you’re using toggles to manage a large number of feature flags it’s important to be able to dynamically re-configure them in-memory. This can save a lot of time during testing.

Many organizations opt to move their toggle configuration into some sort of centralized store. This usually includes some form of admin UI which allows system operators, testers and product managers to view and modify the feature flags and their configuration in a central location. This is a great way to ensure toggles are properly managed and that configuration changes across a fleet of servers are consistently applied.
