When to use

Messages, feedback and other free text answers that run over several lines
Labeled long text fields with a hint under the box, an error state or a disabled state
Profile bios that count characters toward a limit and grow as the user types

When not to use

A comment or prompt box with buttons or a live count inside its border: use the Input Group component
A modal that asks for a note along with reasons to tick, such as a churn survey: use the Dialog blocks
A complete page of fields, such as a support ticket or a profile edit, saved together: use the Form blocks

Agent notes

Textarea grows with its text through field-sizing-content with no height cap, and Chromium ignores rows; set min-h and max-h classes
Only aria-invalid on Textarea turns its border red, in every style; a data-invalid flag on Field leaves the border as it was

Shadcn Textarea: Multi-Line Text Input for Forms

Shadcn Textarea is a semantic HTML textarea element styled with Tailwind and ready for form binding. It follows accessibility best practices by pairing with labels and supporting ARIA invalid states for validation feedback.

Use in contact forms, comment sections, feedback fields, and any form that requires multi-line text input. Pair with React Hook Form or TanStack Form for validation. Shadcn Create style options apply to textarea borders and colors so your design tokens flow into exported code.

ReUI lists textarea components inside contact forms, comment interfaces, and settings with character counts so you evaluate sizing, placeholder clarity, and validation messaging next to real workflows. The sections below explain what it is, why teams use it, which features matter, and how it pairs with form components.

What is Shadcn Textarea?

A textarea is an HTML form control that accepts multi-line text input. Unlike an Shadcn Input, it allows line breaks and is taller by default. Shadcn Textarea is a styled wrapper around the native <textarea> element with Tailwind utilities for borders, padding, and focus states.

Components here show textarea with labels, descriptions, character counters, and placeholder hints. They help you decide sizing (rows prop), whether to allow resizing, and how to handle overflow for long text.

Why Use Shadcn Textarea?

Teams use textareas for user-generated content: feedback, comments, descriptions, and long-form text. A textarea signals to users that multi-line input is expected, unlike a single-line input which suggests brief text only.

The layouts on this page show how to combine a textarea with Shadcn Label, Shadcn Field, and form validation.

Shadcn Textarea Features

Native HTML Textarea. Semantic <textarea> element with Tailwind styling for borders, padding, and focus states. Supports all native HTML attributes.
Resize Control. Allow users to resize via the resize handle (default) or disable with CSS to maintain layout. Customize via Tailwind resize utilities.
Row Height. Set the rows prop to control initial height. Let CSS flex or auto-expand handle dynamic sizing for growing text.
Label and Description. Pair with Shadcn Label via htmlFor and Shadcn Field for descriptions and error messages to guide user input.
Placeholder and Validation. Use clear placeholder text (not a substitute for labels). Add aria-invalid and data-invalid for validation states in forms.

Pair textarea with Shadcn Label and Shadcn Field for organized form layouts with descriptions and validation errors.

Use textarea inside a Shadcn Card for comment or feedback sections. Add a Shadcn Button to submit the comment.

Combine textarea with Shadcn Button to create comment or message submission workflows. Show Shadcn Sonner feedback after submission.

Frequently Asked Questions

How do I auto-resize a textarea as the user types?

Set the rows attribute dynamically based on content height, or use CSS resize: none with max-height and overflow-y: auto for a scrollable box. A common component: useEffect(() => { textarea.style.height = textarea.scrollHeight + 'px' }, [value]).

Can I enforce a character limit on textarea input?

Yes. Use the maxLength HTML attribute: <Textarea maxLength={500} />. Display the current character count with a helper message: <span>{value.length} / 500</span>.

How do I integrate textarea with React Hook Form?

Use register to bind the textarea to form state: const { register } = useForm(); <Textarea {...register('message')} />.

When should I use textarea vs a single-line input?

Use Input for short single-line responses (name, email, search). Use Textarea for longer multi-line content (comments, descriptions, bio, feedback). Consider placeholder text to guide user expectations.

How do I create a markdown input component with a live preview?

Pair the textarea with a preview pane that renders markdown via a library like markdown-it or react-markdown. Update the preview on textarea onChange. Lay out the textarea on the left, preview on the right.

Is textarea accessible to screen readers?

Yes, if paired with a Label via htmlFor. Use ARIA attributes for helper text: aria-describedby="help-text". Announce character count updates with live regions.
