Notes

Textfield is an open text box that allows users to enter and/or edit text into a UI.

There are numerous Textfield props to enable customization of the component. Textfield has multiple different variants to choose from such as outlined, filled, and embedded - a special borderless textfield for inclusion in TopAppBar or TableTopBar.
