There are two types of text field:

Use text fields for entering and editing single lines of text.

Use text areas for entering and editing large amounts of text that require more than a single line.

Use text fields as part of a form or other data collection page for capturing text input.

Use clear labels to indicate what information should be entered into the field.

Use helper text in addition to the field label when additional information helps users understand what information is required.

When setting minimum and maximum values using themin andmax props, make sure to add an indication of these formatting rules in the helper text.

Use placeholder text to optionally provide an example of what to type into the field.

Only use placeholder text if it makes it easier to fill in the text field.

Don't use placeholder text to convey additional meaning other than an example of the expected input.

When including an icon in a text input make sure that the icon is understandable and relevant to the type of input required by the field. Always provide alternative descriptions for icons. Don't use icons if they aren't necessary.

Include a character limit and counter to show how close the current input is to the maximum input length.

Make the width of the field reflect the length of content you expect the user to enter.

Real-time validation helps the user streamline their process and efficiently complete a form. All error validation should be accompanied by an error label. Use inline validation for successes that don't require success labels.
