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.

The function passed to this property enables you to specify a custom condition for UI component closing. For instance, you can prevent closing until a user clicks a certain element.

$(function () {
    $("#popoverContainer").dxPopover({
        // ...
        closeOnOutsideClick: function(e) {
            return e.target === $("#someElement").get()[0];
        }
    });
});

import { DxPopoverModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
    closeOnOutsideClick(e) {
        return e.target === document.getElementById("someElement");
    }
}
@NgModule({
     imports: [
         // ...
         DxPopoverModule
     ],
     // ...
 })

<dx-popover ...
    [closeOnOutsideClick]="closeOnOutsideClick">
</dx-popover>

<template>
    <DxPopover ....
        :close-on-outside-click="closeOnOutsideClick">
    </DxPopover>
</template>

<script>
import 'devextreme/dist/css/dx.light.css';

import DxPopover from 'devextreme-vue/popover';

export default {
    components: {
        DxPopover
    },
    methods: {
        closeOnOutsideClick (e) {
            return e.target === document.getElementById("someElement");
        }
    }
}
</script>

import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import Popover from 'devextreme-react/popover';

const closeOnOutsideClick = (e) => {
    return e.target === document.getElementById("someElement");
};

export default function App() {
    return (
        <Popover ...
            closeOnOutsideClick={closeOnOutsideClick}>
        </Popover>
    );
}

The closeOnOutsideClick function is called when a user clicks the UI component or outside it.

• Customize the Content
• Custom Templates

This property allows you to use CSS for wrapper element configuration. You can customize the shade, resize, and drag zones.

The following markup illustrates relations between wrapper and root elements when you set copyRootClassesToWrapper to true:

<body>

    <!-- The following element is the root element on which the component is initialized. -->
    <!-- Specify classes to be copied to the wrapper element here. -->
    <div id="popover" class="custom-class" ... ></div>

    <!-- The following element is the wrapper element. -->
    <!-- Custom classes are automatically copied from the root element. -->
    <div class="dx-overlay-wrapper dx-popover-wrapper custom-class" ... > 

        <!-- The following element contains component content. -->
        <div class="dx-overlay-content" ... >
            <!-- ... -->
        </div>
    </div>
</body>

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)
  Refer to the W0017 warning description for information on how you can migrate to viewport units.

The Popover calculates its height relative to the window.

If you assign only a string that specifies event names on which the UI component is hidden, the UI component will not apply any delay.

hideEvent: "mouseleave"

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.

• "top" - places the popover over the target element
• "bottom" - places the popover under the target element
• "left" - places the popover to the left of the target element
• "right" - places the popover to the right of the target element

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
});

Shading always applies to the window.

This property supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors
• Paint server address

If you assign only a string that specifies event names on which the UI component is shown, the UI component will not apply any delay.

showEvent: "mouseenter"

This property accepts a value of one of the following types:
