The job of the checkbox is to capture the user’s selection in the form of a marker that fills the checkbox. Checklists, to-do lists, official forms, tax forms, business communications, online questionnaires and tests, academic assessments, psychiatric or psychological evaluation - nearly every such document is a use case for checkboxes. If you think about it, the humble check box is actually one of the most widely used form field types. Moreover, the comb property allows the form to spread the text input evenly across designated spaces. Another important feature is the ability to limit the character count of the input, both at the lower end as well as the upper end. It offers several important advantages, such as multi-line text, spell-checking, and Rich Text support.

This type of field usually accepts any user input, including numeric, alphabet, character, and alphanumeric. They can also be used as password fields, where the user’s input will appear as a string of asterisks, usually with a reveal/hide option next to it.

Text fields may be used to capture a variety of highly variable information such as addresses, names, descriptions, and such unstructured data types.
