How to make netcat and bootstrap menu friends?

Question

HTML

Good afternoon, colleagues!
I'm trying to transfer a site written using bootstrap to CMS Netcat, everything seems to be clear, but I ran into a problem. Namely - in the multi-level menu.
The actual menu code is below:

$subs_arr = array(96);
$headerMenu[0]['prefix'] = "\"; global \$subs_arr, \$headerMenu; \$result.=\"<ul class='navbar-nav'>";
$headerMenu[0]['suffix'] = "</ul>";
$headerMenu[0]['active'] = "<li class='nav-item dropdown'><a \".(in_array(\$data[\$i][Subdivision_ID],\$subs_arr) ? \"class='nav-link dropdown-toggle' id='navbarDropdown' role='button' aria-haspopup='true' aria-expanded='false' data-toggle='dropdown'\":\"class='nav-link'\").\" href='%URL'>%NAME\".s_browse_sub(\$data[\$i][Subdivision_ID],\$headerMenu[1]).\"</a></li>";
$headerMenu[0]['active_link'] = "<li class='nav-item active dropdown'><a \".(in_array(\$data[\$i][Subdivision_ID],\$subs_arr) ? \"class='nav-link dropdown-toggle active' id='navbarDropdown' role='button' aria-haspopup='true' aria-expanded='false' data-toggle='dropdown'\":\"class='nav-link active'\").\" href='%URL'>%NAME\".s_browse_sub(\$data[\$i][Subdivision_ID],\$headerMenu[1]).\"</a></li>";
$headerMenu[0]['unactive'] = "<li class='nav-item dropdown'><a \".(in_array(\$data[\$i][Subdivision_ID],\$subs_arr) ? \"class='nav-link dropdown-toggle' id='navbarDropdown' role='button' aria-haspopup='true' aria-expanded='false' data-toggle='dropdown'\":\"class='nav-link'\").\" href='%URL'>%NAME\".s_browse_sub(\$data[\$i][Subdivision_ID],\$headerMenu[1]).\"</a></li>";
$headerMenu[0]['sortby'] = "Priority ASC";

$headerMenu[1]['prefix'] = "\"; \$headerMenu; \$result.=\"<ul class='dropdown-menu' aria-labelledby='navbarDropdown'>";
$headerMenu[1]['suffix'] = "</ul>";
$headerMenu[1]['active'] = $headerMenu[1]['active_link'] = $headerMenu[1]['unactive'] = "<a class='dropdown-item' href='%URL'>%NAME</a>";
$headerMenu[1]['sortby'] = "Priority ASC";

When executed - everything is fine, except for one detail. When you click on a menu section that has subcategories, something goes wrong, details in the image, please push to solve the problem.

Not relevant already, of course, but I'll leave it for those who will look for the same:
The problem is in the closing tag. It should have been before calling the second level menu.
Thanks for the code, I actually changed it so that the parent category in the query is calculated:

$headerMenu[0]['prefix'] = "\"; global \$headerMenu; \$result.=\"<ul class='navbar-nav'>";
$headerMenu[0]['suffix'] = "</ul>";
$headerMenu[0]['unactive'] = "<li class='nav-item dropdown'><a \".(\$db->get_var(\"Select Parent_Sub_ID FROM Subdivision WHERE Parent_Sub_ID=\".\$data[\$i][Subdivision_ID])!=0 ? \"class='nav-link dropdown-toggle' id='navbardrop' data-toggle='dropdown'\" : \"class='nav-link'\").\"href='%URL'>%NAME</a>\".s_browse_sub(\$data[\$i][Subdivision_ID],\$headerMenu[1]).\"</li>";
$headerMenu[0]['sortby'] = "Priority ASC";

$headerMenu[1]['prefix'] = "\"; \$headerMenu; \$result.=\"<ul class='dropdown-menu' aria-labelledby='navbarDropdown'>";
$headerMenu[1]['suffix'] = "</ul>";
$headerMenu[1]['active'] = $headerMenu[1]['active_link'] = $headerMenu[1]['unactive'] = "<a class='dropdown-item' href='%URL'>%NAME</a>";
$headerMenu[1]['sortby'] = "Priority ASC";
