I am trying to blank out some dropdown boxes and display some static text. Below is what I have. Problem is, once there is a sub-categorie all goes to hell. It can only display the top Category.
$displaylist = array();
$parentlist = array();
make_categories_list($displaylist, $parentlist);
if(isadmin())
{
choose_from_menu($displaylist, "category",
"$form->category", "");
helpbutton("coursecategory", get_string("category"));
}else{
$displaylist[key($displaylist)];
}
