# Long Text (Vue 3)

A Long Text (or Comment) question is a multi-line text input field that allows users to give detailed responses and share their feelings, experiences, or opinions on a subject. Unlike single- or multi-select questions that offer predefined options, a Long Text question asks respondents to express their thoughts in their own words. This example demonstrates how to create and configure a Long text question. Switch between React, Vue, jQuery, Angular, and Vanilla JS to view the example for your JavaScript framework/library.

## Create a Long Text Question

To create a Long Text form field, define an object with the `type` property set to `"comment"` and add it to the [`elements`](https://surveyjs.io/form-library/documentation/pagemodel#elements) array. Within this object, specify the question's [`title`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#title) and a unique [`name`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#name) that identifies the question. Optionally, you can specify a [`description`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#description) to appear under the `title` and a [`placeholder`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#placeholder) to display within the comment area.

## Resize the Comment Area

The comment area of a Long Text question occupies the height of four rows of text on the screen. If you want to change this number and increase or decrease the height, set the [`rows`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#rows) property.

When the content exceeds the comment area, a vertical scrollbar appears. Enable the [`autoGrow`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#autoGrow) property if you want the comment area to automatically expand or shrink to accommodate the content and thus remove the scrollbar. You can also enable `SurveyModel`'s [`autoGrowComment`](https://surveyjs.io/form-library/documentation/api-reference/survey-data-model#autoGrowComment) property to activate the same feature for all comment areas in a survey.

A Long Text question displays a resize handle that allows users to resize the comment area. If you want to hide the handle, disable the [`allowResize`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#allowResize) property in an individual Long Text question's configuration or the [`allowResizeComment`](https://surveyjs.io/form-library/documentation/surveymodel#allowResizeComment) in `SurveyModel`. The latter property hides the resize handle for all comment areas.

## Limit the Number of Input Characters

A Long Text form field accepts an unlimited number of characters. If you want to set a limit, use the [`maxLength`](https://surveyjs.io/form-library/documentation/api-reference/comment-field-model#maxLength) property. With this setting, the comment area displays a character count.
