    You may override the setChecked method of the TreeNode as follows to achieve the required functionality:
    var oldFn = wijmo.nav.TreeNode.prototype.setChecked;
    wijmo.nav.TreeNode.prototype.setChecked = function(checked) {
    let cb = this.checkBox;
    cb.checked = checked;
    cb.indeterminate = false;

    You may also refer to the following sample which demonstrates the same:

    Thanks, that's great.

    But I have problem that I have used formatItem to insert a select list beside the item but I want to set align it to right.

    And another thing that when I select the select list it just close right after that.

    Can you help with that?

    Thank you for providing the sample.
    To right-align the select, you may set it float CSS to right.
    .wj-node select{
    float: right;

    To prevent the select from autoclosing, you may handle the click event and call prevent default. Please refer to the following updated sample and let us know if you face any issues:
