Selection
By default, selection in the TreeList is disabled.
To boost the performance of the TreeList when it is rendering a huge number of items and selection is enabled, use paging and a reasonable page size.
The Kendo UI Treelist exposes different modes of row selection:
Row Selection
To enable the selection functionality of the TreeList, set the selectable option to true. As a result, the default single-row selection functionality will be applied.
selectable: true,
Single Row Checkbox Selection
To enable checkbox selection, add a column to the columns collection of the TreeList and set the selectable option to true:
<script>
$("#treelist").kendoTreeList({
columns: [
{ selectable: true },
// ...
]
});
</script>
In order to select or deselect all of the child items of the currently selected row, enable the includeChildren option:
<script>
$("#treelist").kendoTreeList({
columns: [
{ selectable: true, includeChildren: true },
// ...
]
});
</script>
The TreeList does not support the simultaneous usage of the built-in checkbox-column selection and the selection which is enabled through the selectable option.
