Does your website or app have any toggle components? If it does, it's essential to understand how to use them correctly so you don't confuse users when they configure settings.
A common mistake is to mix binary logic with toggle segments. In other words, designers will include "On/Off" options in the component. Not only that, but they may also have a "Custom" option that allows users to configure the setting. Combining all this into a toggle segment is wrong and confusing.
