, Menu problems

Online, etc. menu question Product Table. The structure is FieldTypeCollationNullKey & nbsp; ------------------------------------------------ c_idint (11) (NULL) online, etc. Menu Question
The structure of the product table is as follows:
Field Type Collation Null Key
------------------------------------------------
C_id int (11) (NULL) NO PRI
C_pid int (11) (NULL) YES
C_path varchar (255) utf8_general_ci YES
C_name varchar (255) utf8_general_ci YES

This is the function I wrote to get the menu.

PHP code

  function menuhead($pid=0){    global $mydb;    $rs=$mydb->query("select c_id,c_pid,c_name from pdt_catagories where c_pid=".$pid."");    if ($rs->rnum())    {        echo '
  
  

   
   ';        while ($f=$rs->movenext())        {            echo '
   
   
'; if (!$pid) echo ''.$f["c_name"].''; else echo ''.displaystr($f["c_name"],26).''; echo $pid?'':'
'; menuhead($f["c_id"]); echo $pid?'':'
'; echo '
';        }        echo '
  
  
';    }}

I want to make it like this. how can I write it? the main reason is that the CSS style does not work?


------ Solution --------------------
This is js, and this does not require data. it is similar to the navigation menu. you can search for the sliding menu.
