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 PivotGridFieldChooser UI component in an application executed on the desktop.

jQuery

JavaScript

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

Angular

TypeScript

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

Vue

<template>
    <div>
        <DxPivotGridFieldChooser id="pivotGridFieldChooser1" />
        <DxPivotGridFieldChooser id="pivotGridFieldChooser2" />
    </div>
</template>
<script>
import DxPivotGridFieldChooser from "devextreme-vue/pivot-grid-field-chooser";
import PivotGridFieldChooser from "devextreme/ui/pivot_grid_field_chooser";

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

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

React

import React from "react";
import dxPivotGridFieldChooser from "devextreme/ui/pivot_grid_field_chooser";
import PivotGridFieldChooser from "devextreme-react/pivot-grid-field-chooser";

class App extends React.Component {
    render () {
        dxPivotGridFieldChooser.defaultOptions({
            device: { deviceType: "desktop" },
            options: {
                // Here go the PivotGridFieldChooser options
            }
        })
        return (
            <div>
                <PivotGridFieldChooser id="pivotGridFieldChooser1" />
                <PivotGridFieldChooser id="pivotGridFieldChooser2" />
            </div>
        )
    }
}

export default App;

dispose()

Disposes of all the resources allocated to the PivotGridFieldChooser instance.

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

JavaScript

$("#myPivotGridFieldChooser").dxPivotGridFieldChooser("dispose");
$("#myPivotGridFieldChooser").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-pivot-grid-field-chooser ...
    *ngIf="condition">
</dx-pivot-grid-field-chooser>

Vue

App.vue

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

<script>
import DxPivotGridFieldChooser from 'devextreme-vue/pivot-grid-field-chooser';

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

React

App.js

import React from 'react';

import PivotGridFieldChooser from 'devextreme-react/pivot-grid-field-chooser';

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

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

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