defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the SlideOutView UI component in an application executed on the desktop.

jQuery
JavaScript
DevExpress.ui.dxSlideOutView.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the SlideOutView properties
    }
});
Angular
TypeScript
import SlideOutView from "devextreme/ui/slide_out_view";
// ...
export class AppComponent {
    constructor () {
        SlideOutView.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the SlideOutView properties
            }
        });
    }
}
Vue
<template>
    <div>
        <DxSlideOutView id="slideOutView1" />
        <DxSlideOutView id="slideOutView2" />
    </div>
</template>
<script>
import DxSlideOutView from "devextreme-vue/slide-out-view";
import SlideOutView from "devextreme/ui/slide_out_view";

SlideOutView.defaultOptions({
    device: { deviceType: "desktop" },
    options: {
        // Here go the SlideOutView properties
    }
});

export default {
    components: {
        DxSlideOutView
    }
}
</script>
React
import React, {useEffect} from "react";
import dxSlideOutView from "devextreme/ui/slide_out_view";
import SlideOutView from "devextreme-react/slide-out-view";

export default function App() {
    useEffect(() => { 
        dxSlideOutView.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the SlideOutView properties
            }
        })
    });

    return (
        <div>
            <SlideOutView id="slideOutView1" />
            <SlideOutView id="slideOutView2" />
        </div>
    )
}

dispose()

Disposes of all the resources allocated to the SlideOutView instance.

After calling this method, remove the DOM element associated with the UI component:

JavaScript
$("#mySlideOutView").dxSlideOutView("dispose");
$("#mySlideOutView").remove();

Use this method only if the UI component was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:

Angular
app.component.html
<dx-slide-out-view ...
    *ngIf="condition">
</dx-slide-out-view>
Vue
App.vue
<template>
    <DxSlideOutView ...
        v-if="condition">
    </DxSlideOutView>
</template>

<script>
import DxSlideOutView from 'devextreme-vue/slide-out-view';

export default {
    components: {
        DxSlideOutView
    }
}
</script>
React
App.js
import React from 'react';

import SlideOutView from 'devextreme-react/slide-out-view';

function DxSlideOutView(props) {
    if (!props.shouldRender) {
        return null;
    }

    return (
        <SlideOutView ... >    
        </SlideOutView>
    );
}

class App extends React.Component {
    render() {
        return (
            <DxSlideOutView shouldRender="condition" />
        );
    }
}
export default App;
