Remove parent checkbox in EJ2 JavaScript TreeView control

28 Jan 20256 minutes to read

By enabling the showCheckBox property, you can render a checkbox before each node of the TreeView. However, some applications require checkboxes to be displayed only in child nodes. In such cases, you can remove the checkbox of the parent node by customizing the CSS.

    { id: 1, name: 'India', hasChild: true, expanded: true },

    { id: 3, pid: 1, name: 'Bihar' },
