area
Specifies the area within which users can resize the UI component.
You can use a selector string, jQuery object, or DOM element to specify this property:

jQuery object
JavaScriptarea: $('.test-div')
DOM element
JavaScriptarea: $('.test-div')[0]
elementAttr
Specifies the global attributes to be attached to the UI component's container element.
jQuery
$(function(){ $("#resizableContainer").dxResizable({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-resizable ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-resizable>
import { DxResizableModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxResizableModule ], // ... })
Vue
<template> <DxResizable ... :element-attr="resizableAttributes"> </DxResizable> </template> <script> import DxResizable from 'devextreme-vue/resizable'; export default { components: { DxResizable }, data() { return { resizableAttributes: { id: 'elementId', class: 'class-name' } } } } </script>
React
import React from 'react'; import Resizable from 'devextreme-react/resizable'; class App extends React.Component { resizableAttributes = { id: 'elementId', class: 'class-name' } render() { return ( <Resizable ... elementAttr={this.resizableAttributes}> </Resizable> ); } } export default App;
handles
Specifies which borders of the UI component element are used as a handle.
You can pass several values separated by a space. For example, "right bottom".
height
Specifies the UI component's height.
This property accepts a value of one of the following types:
Number
The height in pixels.String
A CSS-accepted measurement of height. For example,"55px"
,"20vh"
,"80%"
,"inherit"
.Function (deprecated since v21.2)

$(function(){ $("#resizable").dxResizable({ // ... keepAspectRatio: false }); });
Angular
<dx-resizable ... [keepAspectRatio]="false"> </dx-resizable>
Vue
<template> <DxResizable ... :keep-aspect-ratio="false" /> </template> <script> // ... </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Resizable from 'devextreme-react/resizable'; function App() { return ( <Resizable ... keepAspectRatio={false} /> ); } export default App;
