jQuery

JavaScript

DevExpress.ui.dxMultiView.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the MultiView options
    }
});

Angular

TypeScript

import MultiView from "devextreme/ui/multi_view";
// ...
export class AppComponent {
    constructor () {
        MultiView.defaultOptions({
            device: { deviceType: "desktop" },
            options: {

            }
        });

$("#myMultiView").remove();

Angular

HTML

<dx-multi-view #multiViewVar id="myMultiView"></dx-multi-view>

export class AppComponent {
    @ViewChild("multiViewVar") multiView: DxMultiViewComponent;
