columns.selectable Boolean (default: false)

If set to true the grid will render a select column with checkboxes in each cell, thus enabling multi-row selection. The header checkbox allows users to select/deselect all the rows on the current page. The change event is fired when a row is selected.

More about the Grid Selection feature you can find in this documentation article.

Example - enable multi-row selection by adding a select column with checkboxes

<div id="grid"></div>
<script>
$("#grid").kendoGrid({
  columns: [
    { selectable: true },
    { field: "name" }
  ],
  dataSource: [ { name: "Jane Doe" }, { name: "John Doe" } ]
});
</script>
