Header in popup items is possible in DropdownButton by templating entire popup with ListView.
Create ListView with id #listview
and provide it as a
target
for DropDownButton.
In the following example, ListView element is given as target
to DropDownButton and header
can be achieved by groupBy
property.
import { enableRipple } from '@syncfusion/ej2-base';
import { ListViewComponent } from '@syncfusion/ej2-react-lists';
import { DropDownButtonComponent } from '@syncfusion/ej2-react-splitbuttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';
enableRipple(true);
// To render DropDownButton.
class App extends React.Component {
constructor() {
super(...arguments);
this.data = [
{ class: 'data', text: 'Print', id: 'data1', category: 'Customize Quick Access Toolbar' },
{ class: 'data', text: 'Save As', id: 'data2', category: 'Customize Quick Access Toolbar' },
{ class: 'data', text: 'Update Folder', id: 'data3', category: 'Customize Quick Access Toolbar' },
{ class: 'data', text: 'Reply', id: 'data4', category: 'Customize Quick Access Toolbar' }
];
this.field = { text: 'text', groupBy: 'category' };
}
render() {
return (<div>
<ListViewComponent id="listview" dataSource={this.data} fields={this.field} showCheckBox={true}/>
<DropDownButtonComponent target='#listview' iconCss='e-icons e-down' cssClass='e-caret-hide'/>
</div>);
}
}
ReactDom.render(<App />, document.getElementById('button'));
