Set this object to null or undefined to disable animation.

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

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

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

The container is defined during the widget's initialization. The container by default is the viewport. If the viewport is not found, it is the body element. If the viewport and the body element are absent, the container is the parent element.

You can use the position.of option and the Popover's target option to specify the element against which the widget will be positioned. If you set both these options, position.of takes precedence.

Besides the position configuration object, the option 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 option is set to true, the widget 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
});
