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 widget:

JavaScript

$("#myPivotGridFieldChooser").dxPivotGridFieldChooser("dispose");
$("#myPivotGridFieldChooser").remove();

Use this method only if the widget 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 (
