Items in popup can be grouped in SplitButton by templating entire popup with ListView. To achieve grouping in ListView,
check ListView Grouping
documentation. To template ListView in popup, create
ListView with id listview
and provide it as target
for SplitButton.
The following example illustrates how to group items in popup using ListView component.
ej.base.enableRipple(true);
var listItems = [
{
'text': 'Cut',
'category': 'Basic'
},
{
'text': 'Copy',
'category': 'Basic'
},
{
'text': 'Paste',
'category': 'Basic'
},
{
'text': 'Paste as Formula',
'category': 'Advanced'
},
{
'text': 'Paste as Hyperlink',
'category': 'Advanced'
},
];
var listView = new ej.lists.ListView({
dataSource: listItems,
fields: { groupBy: 'category' }
}, '#listview');
var splitBtn = new ej.splitbuttons.SplitButton({ content: 'ClipBoard', target: listView.element }, '#element');
