requires the effect. When any checkbox is clicked, all the parents are automatically selected. The parents and subsets are separate and not fully selected. The code structure is as follows 

[
        {
            "id": 1,
            "display_name": "",
            "children": []
        },
        {
            "id": 2,
            "display_name": "",
            "children": [
                {
                    "id": 3,
                    "display_name": "",
                    "children": [
                        {
                            "id": 5,
                            "display_name": ""
                        },
                        {
                            "id": 6,
                            "display_name": ""
                        },
                        {
                            "id": 7,
                            "display_name": "/"
                        },
                        {
                            "id": 8,
                            "display_name": ""
                        }
                    ]

if the number of layers is determined, you can do this: 

<script>
    var ad = [
        {
            "id": 1,
            "display_name": "",
            "children": []
        },
        {
            "id": 2,
            "display_name": "",
            "children": [
                {
                    "id": 3,
                    "display_name": "",
                    "children": [
                        {
                            "id": 5,
                            "display_name": ""
                        },
                        {
                            "id": 6,
                            "display_name": ""
                        },
                        {
                            "id": 7,
                            "display_name": "/"
                        },
                        {
                            "id": 8,
                            "display_name": ""
                        }
                    ]
                }
            ]
        }];

    var the_id = 5;
    var the_select_id = [];

    for(var i in ad){
        if (ad[i].id !== the_id) {
            for(var j in ad[i].children) {

                if (ad[i].children[j].id !== the_id) {
                    for(var k in ad[i].children[j].children) {

                        if (ad[i].children[j].children[k].id == the_id) {
                            the_select_id.push(ad[i].children[j].children[k].id);
                            the_select_id.push(ad[i].children[j].id);
                            the_select_id.push(ad[i].id);
                        }
                    }
                } else {
                    the_select_id.push(ad[i].children[j].id);
                    the_select_id.push(ad[i].id);
                }
            }
        } else {
            the_select_id.push(ad[i].id);
        }
    }

    console.log(the_select_id);
</script>

of course, the code can also be streamlined and optimized, which is just a reference
