Question about SMARTY display classification
I made a classification, including top-level classification and secondary classification.

$ Questionfl = $ page-> pagesql ("select * from questionfl where sid = false"); // you can specify a top-level category.
$ Q = 0;
While ($ flrows = $ questionfl-> fetchRow ()){
$ Listfl [$ q] ["id"] = $ flrows ["id"];
$ Listfl [$ q] ["name"] = $ flrows ["name"];

$ Questionsl = $ page-> pagesql ("select * from questionfl where sid = '". $ listfl [$ q] ["id"]. "'"); // level 2 classification
$ S = 0;
While ($ slrows = $ questionsl-> fetchRow ()){
$ Listsl [$ s] ["id"] = $ slrows ["id"];
$ Listsl [$ s] ["name"] = $ slrows ["name"];
$ Listsl [$ s] ["sid"] = $ slrows ["sid"];
$ S ++;
}
$ Q ++;
}
