The Popover component shows pop-up notifications within a box with an arrow that points to a specified UI element. In this demo, you can hover the mouse pointer over one of the details labels or click the more link to display Popover.

Attach Popover to a Page Element

Popover displays an arrow that points to a page element. To specify the element, set the target property to a CSS selector. In this demo, target elements are selected by id.

You can use the position property to position Popover relative to the target element. If you do not specify this property, Popover is displayed under the element.

Show and Hide Popover

The showEvent and hideEvent properties allow you to show and hide Popover in response to certain events. These properties can accept one or multiple names of DOM events or DevExtreme UI events separated by a space character.

You can also specify a delay before the events occur. Set the showEvent and hideEvent properties to an object with the name (one or multiple event names) and delay properties.

In this demo, the last Popover appears when you click its target element because its showEvent property is set to the DevExtreme dxclick event. Other Popover components appear and disappear on the mouseenter and mouseleave DOM events.

Specify Content

Popover consists of content area and a title. You can specify static content in the HTML markup as shown in this demo. If Popover should display dynamic content, use the contentTemplate property to specify a template. To display the title, enable the showTitle property and set the title property to the title text.

Animate Popover

If you want to show and hide Popover with animation effects, assign an object with the show and hide fields to the animation property. Each of these fields accepts an object that configures the animation type and other properties. In this demo, Popover appears with a pop-up animation and fades away when it disappears.

Shade the Background

You can show Popover with a shaded background. To do this, enable the shading property and specify a shadingColor.
