multilinetextarea

Multilinetextarea is a user interface control designed to collect more than one line of text from a user. It is typically implemented as a multiline input field and is used for notes, comments, descriptions, and other longer text values. In web applications, multilinetextarea is most commonly realized with the textarea element, which preserves line breaks and allows free-form text entry. Frameworks and libraries may wrap this element in a component that adds features such as validation, autosizing, or custom styling.

Common attributes include placeholder, rows, cols for size, wrap to control how text flows, maxlength to limit input, and standard form attributes such as name, required, disabled, readOnly, autofocus, and autocomplete. The content can be accessed as the element's value or bound to state in reactive frameworks. Events such as input and change report user edits.

Accessibility: to be usable by assistive technology, the control should be associated with a label, and if necessary ARIA attributes should indicate its multiline nature. Keyboard users rely on standard navigation, Tab and Shift-Tab to move focus, and Enter keys can insert line breaks depending on configuration.

Behavior and styling: browsers provide a default resizable area; CSS resize controls whether it can be resized and in which directions. Developers may implement autosizing to grow the height with content, or constrain the height to create a scrollable region.

Relation and usage: Multilinetextarea is related to single-line input controls and other multiline editors like rich-text editors. It remains a versatile element across desktop and mobile interfaces for collecting user-generated text.
