let more = h ("Select", {

)

                props:{
                    value: tmp_value,
                    placeholder: this.$t("userList.selectRole"),
                    clearable: true,
                    transfer: true,
                    "element-id":"select" + data.uuid,
                },
                on:{
                    input:function(role){
                        if(data.tree_type == "group"){
                            _this.$set(_this.groupRoles, data.uuid, role)
                        }else{
                            _this.$set(_this.resourceRoles, data.uuid, role)
                        };
                        
                    },
                },
            },options);

what result do you expect? What is the error message actually seen?

think of using the two-way binding of Select to implement. The parent changes the Select and then Synchronize changes the value, of the child Select, but it doesn"t seem to work. Ask the boss for guidance
