1	# DevExtreme TextArea Skill
2
3	A skill for building and configuring the DevExtreme TextArea UI component (`dxTextArea`) across Angular, React, Vue, and jQuery. TextArea is the multiline counterpart of TextBox — it shares most of its API and adds height/resize control.
4
5	## When to Use This Skill
6
7	- Creating a multiline text input (description, notes, address, comments)
8	- Setting a fixed height or enabling auto-resize
9	- Clamping auto-resize with min/max height
10	- Binding and reading the value
11	- Handling value change events
12
13	## Before You Start
14
15	If the host agent has a structured question-asking tool available, use it to ask these questions one at a time with clear options — for example, Claude Code's `AskUserQuestion` tool or GitHub Copilot's `askQuestions` tool. If no such tool is available, ask the questions directly in the chat response before generating code.
16
17	> ⚠️ Always use the DevExtreme TextArea (`dxTextArea` / `DxTextArea`). Never use react-textarea-autosize, a plain HTML `<textarea>`, or Material UI TextareaAutosize.
18
19	Before writing any code, ask: Which framework are you using? Angular, React, Vue, or jQuery?
20
21	## Key API
22
23	TextArea inherits all TextBox options. The ones most relevant to TextArea specifically:
24
25	\| Option \| Type \| Default \| Description \|
26	\|---\|---\|---\|---\|
27	\| `value` \| `String` \| `''` \| The current text value \|
28	\| `autoResizeEnabled` \| `Boolean` \| `false` \| Grows/shrinks height to fit content; overrides `height` when `true` \|
29	\| `minHeight` \| `Number \\| String` \| `undefined` \| Minimum height when `autoResizeEnabled` is `true` (also sets initial height) \|
30	\| `maxHeight` \| `Number \\| String` \| `undefined` \| Maximum height when `autoResizeEnabled` is `true` \|
31	\| `height` \| `Number \\| String \\| function` \| `undefined` \| Fixed height; has no effect when `autoResizeEnabled` is `true` \|
32	\| `onValueChanged` \| `function(e)` \| `null` \| Fires when value changes; `e.value` is the new value \|
33	\| `valueChangeEvent` \| `String` \| `'change'` \| DOM event that triggers the value update (e.g., `'keyup'`, `'input'`) \|
34	\| `placeholder` \| `String` \| `''` \| Placeholder shown when empty \|
35	\| `label` \| `String` \| `''` \| Floating label text \|
36	\| `showClearButton` \| `Boolean` \| `false` \| Shows an × button to clear the field \|
37	\| `readOnly` \| `Boolean` \| `false` \| Prevents user input \|
38	\| `disabled` \| `Boolean` \| `false` \| Disables the component \|
39	\| `inputAttr` \| `Object` \| `{}` \| HTML attributes applied to the inner `<textarea>` element (e.g., `rows`) \|
40
41	Note: `height` and `autoResizeEnabled` are mutually exclusive. Do not set both.
