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 Drawer UI component in an application executed on the desktop.

jQuery

JavaScript

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

Angular

TypeScript

import Drawer from "devextreme/ui/drawer";
// ...
export class AppComponent {
    constructor () {
        Drawer.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the Drawer properties
            }
        });
    }
}

Vue

<template>
    <div>
        <DxDrawer id="drawer1" />
        <DxDrawer id="drawer2" />
    </div>
</template>
<script>
import DxDrawer from "devextreme-vue/drawer";
import Drawer from "devextreme/ui/drawer";

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

export default {
    components: {
        DxDrawer
    }
}
</script>

React

import React, {useEffect} from "react";
import dxDrawer from "devextreme/ui/drawer";
import Drawer from "devextreme-react/drawer";

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

    return (
        <div>
            <Drawer id="drawer1" />
            <Drawer id="drawer2" />
        </div>
    )
}

dispose()

Disposes of all the resources allocated to the Drawer instance.

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

JavaScript

$("#myDrawer").dxDrawer("dispose");
$("#myDrawer").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-drawer ...
    *ngIf="condition">
</dx-drawer>

Vue

App.vue

<template>
    <DxDrawer ...
        v-if="condition">
    </DxDrawer>
</template>

<script>
import DxDrawer from 'devextreme-vue/drawer';

export default {
    components: {
        DxDrawer
    }
}
</script>

React

App.js

import React from 'react';

import Drawer from 'devextreme-react/drawer';

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

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

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

...
let element = document.getElementById("myDrawer");
let instance = Drawer.getInstance(element) as Drawer;
