OO.ui.MultilineTextInputWidget

Extends

Constructor

new OO.ui.MultilineTextInputWidget([config]) #

MultilineTextInputWidgets, like HTML textareas, are featuring customization options to configure number of rows visible. In addition, these widgets can be autosized to fit user inputs and can show icons and indicators. Please see the OOUI documentation on MediaWiki for more information and examples.

MultilineTextInputWidgets can also be used when a single line string is required, but we want to display it to the user over mulitple lines (wrapped). This is done by setting the allowLinebreaks config to false.

This widget can be used inside an HTML form, such as a OO.ui.FormLayout.

Example

// A MultilineTextInputWidget.
    const multilineTextInput = new OO.ui.MultilineTextInputWidget( {
        value: 'Text input on multiple lines'
    } );
    $( document.body ).append( multilineTextInput.$element );

Parameters:

Name Type Attributes Description
config Object optional

Configuration options

Properties:
Name Type Attributes Default Description
rows number optional

Number of visible lines in textarea. If used with autosize, specifies minimum number of rows to display.
autosize boolean optional
 false

Automatically resize the text input to fit its content. Use the #maxRows config to specify a maximum number of displayed rows.
maxRows number optional

Maximum number of rows to display when #autosize is set to true. Defaults to the maximum of 10 and 2 * rows, or 10 if rows isn't provided.
allowLinebreaks boolean optional
 true

Whether to allow the user to add line breaks.
