WAI-ARIA: aria-multiline (Property)
Description
Indicates whether a text box accepts multiple lines of input or only a single line.
Note: In most user agent implementations, the default behavior of the ENTER or RETURN key is different between the single-line and multi-line text fields in HTML. When user has focus in a single-line <input type=”text”> element, the keystroke usually submits the form. When user has focus in a multi-line <textarea> element, the keystroke inserts a line break. The WAI-ARIA textbox role differentiates these types of boxes with the aria-multiline attribute, so authors are advised to be aware of this distinction when designing the field.
