The Right Way to Use a Toggle Component in Your Web Application

February 28, 2024 by No Comments


Toggle is a simple user interface component that can make a big impact on the way users interact with your product. They are useful when you need to provide users with a simple choice between opposing states – for example to update their preferences, settings or other types of information. However, using toggles requires a lot of care to ensure that they are used effectively and they are always accessible for all users. For instance, not all users can use colors to distinguish on from off and it’s often difficult for screen readers and other assistive technologies to determine which side of a toggle is currently active.

The most important thing to remember when using toggles is that they must be clear and direct in their labels, so that the user knows exactly what state the switch is currently in. Also, they should only be used when a simple choice needs to be made and that choice will have an immediate effect on the user’s experience. If you’re using them to hide content in a particular section of an article, for instance, this can have a negative impact on the overall reading experience as well as on the ability to track how many people view that section.

In terms of development, a toggle system can be a great asset to your CI/CD processes as it allows developers and testers to dynamically re-configure a specific service instance. However, if used in the wrong context it can be a very dangerous tool and cause a lot of pain for your users. For this reason it’s usually best to build out some form of admin UI to allow for controlled re-configuration of feature flags.
