You can add placeholders into Text, Number, and Email Address input nodes. A placeholder is text that appears in the field, in a grayed-out format, and provides a hint to the end user about what they should enter. As soon as the end user begins typing in the field, the placeholder disappears.
Placeholders can be used to illustrate an example of a potential response. This is particularly beneficial when the end user's input must adhere to specific guidelines, such as allowing only capital letters.
