To add a CheckBox to nodes in TreeView (a web component that you can use in Angular, React and Vue), you can use the built-in feature for checkboxes or modify the item template. Using the getFullList method maintains high performance, because instead going through the tree hierarchy you are working with a linear list. We are comparing the check value of each item object against the selected option in the combo box, if it matches the item is added to the list. To populate the list (represented by the List component), we are using the getFullList method from TreeView, which retrieves a flat list of all items in the tree hierarchy.

Otherwise if there is at least one child item with checked or indeterminate state, set the parent checkbox value to indeterminate. If the number is equal, then the parent checkbox value is checked. Then, compare these values to number of child items. Next, for each parent calculate how many child items have its checkState in checked and indeterminate value separately.
