defaultOptions(rule)
defaultOptions is a static method that the widget class supports. The following code demonstrates how to specify default options for all instances of the Accordion widget in an application executed on the desktop.
jQuery
DevExpress.ui.dxAccordion.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Accordion options } });
Angular
import Accordion from "devextreme/ui/accordion"; // ... export class AppComponent { constructor () { Accordion.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Accordion options } }); } }
Vue
<template> <div> <DxAccordion id="accordion1" /> <DxAccordion id="accordion2" /> </div> </template> <script> import DxAccordion from "devextreme-vue/accordion"; import Accordion from "devextreme/ui/accordion"; Accordion.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Accordion options } }); export default { components: { DxAccordion } } </script>
React
import React from "react"; import dxAccordion from "devextreme/ui/accordion"; import Accordion from "devextreme-react/accordion"; class App extends React.Component { render () { dxAccordion.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Accordion options } }) return ( <div> <Accordion id="accordion1" /> <Accordion id="accordion2" /> </div> ) } } export default App;
dispose()
After calling this method, remove the DOM element associated with the widget:
$("#myAccordion").dxAccordion("dispose"); $("#myAccordion").remove();
Use this method only if the widget was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
<dx-accordion ... *ngIf="condition"> </dx-accordion>
Vue
<template> <DxAccordion ... v-if="condition"> </DxAccordion> </template> <script> import DxAccordion from 'devextreme-vue/accordion'; export default { components: { DxAccordion } } </script>
React
import React from 'react'; import Accordion from 'devextreme-react/accordion'; function DxAccordion(props) { if (!props.shouldRender) { return null; } return ( <Accordion ... > </Accordion> ); } class App extends React.Component { render() { return ( <DxAccordion shouldRender="condition" /> ); } } export default App;
