An object defining configuration properties for the Popover UI component.
Configures UI component visibility animations. This object contains two fields: show and hide.
The following code specifies the default value of the object:
{ show: { type: 'fade', from: 0, to: 1 }, hide: { type: 'fade', from: 1, to: 0 } }
Set this object to null
or undefined
to disable animations.

This property accepts one of the following values:
A CSS selector, or a jQuery selector if you use jQuery
jQuery$(function(){ $("#popoverContainer").dxPopover({ // ... container: '#containerElement' }); });Angular

<template> <DxPopover ... container="#containerElement" > </DxPopover> </template> <script> import { DxPopover } from 'devextreme-vue/popover'; export default { components: { DxPopover } }; </script>React
import Popover from 'devextreme-react/popover'; // ... function App() { return ( <Popover ... container="#containerElement" > </Popover> ); }
A jQuery wrapper
jQuery$(function(){ $("#popoverContainer").dxPopover({ // ... container: $('#containerElement') }); });
A DOM element
jQuery$(function(){ $("#popoverContainer").dxPopover({ // ... container: document.getElementById('#containerElement') }); });Angular
<dx-popover ... [container]="containerElement" > </dx-popover>
// ... export class AppComponent { containerElement: Element; constructor() { this.containerElement = document.getElementById('#containerElement') as Element; } }Vue
<template> <DxPopover ... :container="containerElement" > </DxPopover> </template> <script> import { DxPopover } from 'devextreme-vue/popover'; export default { components: { DxPopover }, data() { return { containerElement: null } }, mounted() { this.containerElement = document.getElementById('containerElement'); } }; </script>React

The UI component defines the default container on its initialization. This default container can be one of the following (if the element is absent, the component selects the next one):
.dx-viewport
body

Selector: content-template
Default Name: 'content'
Specifies whether to render the UI component's content when it is displayed. If false, the content is rendered immediately.
Selector: defer-rendering
Default Value: true
AngularIf you set the deferRendering
property to true, wrap the content in the Angular named template.
If you set the deferRendering
property to true, wrap the content in the Vue named template.

An object defining UI component positioning properties.
Selector: DxPosition
Default Value: { my: 'top center', at: 'bottom center', collision: 'fit flip' }
You can use the position.of property and the Popover's target property to specify the element against which the UI component will be positioned. If you set both these properties, position.of takes precedence.
Besides the position configuration object, the property can take on the following string values, which are shortcuts for the corresponding position configuration.
Switches the UI component to a right-to-left representation.
Selector: rtl-enabled
Default Value: false
When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.
DevExpress.config({ rtlEnabled: true });

A Boolean value specifying whether or not the UI component is visible.
Specifies the UI component's width.
This property accepts a value of one of the following types:
Number
The width in pixels.
String

Selector: wrapper-attr
Type: any
Default Value: {}
jQuery$(function(){ $("#popoverContainer").dxPopover({ // ... wrapperAttr: { id: "elementId", class: "class-name" } }); });Angular
<dx-popover ... [wrapperAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-popover>
import { Component } from '@angular/core'; // ... @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { // ... }

The code above specifies the id
and class
attributes for the wrapper element and produces markup similar to this:
<body> <!-- The following is the wrapper element. --> <!-- It is nested inside an element defined by the `container` property (`<body>` by default). --> <div id="elementId" class="dx-overlay-wrapper dx-popover-wrapper class-name" ... > <!-- The following element contains component content. --> <div class="dx-overlay-content"> <!-- The following element displays content specified in the `contentTemplate`. --> <div class="dx-popup-content" ... > <!-- ... --> </div> </div> </div> </body>jQuery
