The ListView control supports wrapping list items into a group based on the category. The category of each list item can be mapped with groupBy field of the data source. You can display grouped list items count in the list-header using the group header template. Refer to the following code sample to display grouped list item count.
var template = '<div class="e-list-wrapper e-list-multi-line e-list-avatar">' +
'<img class="e-avatar e-avatar-circle" src=${image} style="background:#BCBCBC" />' +
'<span class="e-list-item-header">${Name}</span>' +
'<span class="e-list-content">${contact}</span>' +
'</div>';
//Define an array of JSON data
var dataSource = [
{ Name: 'Nancy', contact:'(206) 555-985774', id: '1', image: 'https://ej2.syncfusion.com/demos/src/grid/images/1.png', category: 'Experience'},
