Menu Items Not Closing? - php

Question

I'm coding a staff panel but I'm stuck I've added a menu (navigation) but I'm stuck on how to go about opening it when clicked and closing it when clicked if open.
Here is the code i have so far;
<ul id="menu" class="nav">
<?php
$url = $_GET['url'] ? $core->clean($_GET['url']) : 'core.home';
$query3 = $db->query("SELECT * FROM menu WHERE url = '{$url}'");
$array3 = $db->assoc($query3);
if (!$array3['usergroup']) {
$array3['usergroup'] = "invalid";
}
$query = $db->query("SELECT * FROM usergroups ORDER BY weight ASC");
while ($array = $db->assoc($query)) {
if (in_array($array['id'], $user->data['uGroupArray'])) {
?>
<div class="menustyle" onclick="Radi.menuToggle('<?php echo $array['id']; ?>');">
<div class="menutext"><?php echo $array['name']; ?></div>
</div>
<ul>
<li class="menuitems"<?php if ($array['id'] != $array3['usergroup']) { ?> onclick="Radi.menuToggle('<?php echo $array['id']; ?>');" style="display: none;"<?php } ?> id="mitems_<?php echo $array['id']; ?>">
<?php
$query2 = $db->query("SELECT * FROM menu WHERE usergroup = '{$array['id']}' AND visible = '1' ORDER BY weight ASC");
$i = "a";
while ($array2 = $db->assoc($query2)) {
?>
<li>
<?php echo $array2['text']; ?>
</li>
<?php
$i++;
if ($i == "c") {
$i = "a";
}
}
?>
</ul>
</li>
<?php
}
}
?>
</li>
</ul>
</div>
And this is the defualt code when you download radipanel;
<div style="float: left; width: 200px;">
<?php
$url = $_GET['url'] ? $core->clean($_GET['url']) : 'core.home';
$query3 = $db->query("SELECT * FROM menu WHERE url = '{$url}'");
$array3 = $db->assoc($query3);
if (!$array3['usergroup']) {
$array3['usergroup'] = "invalid";
}
$query = $db->query("SELECT * FROM usergroups ORDER BY weight ASC");
while ($array = $db->assoc($query)) {
if (in_array($array['id'], $user->data['uGroupArray'])) {
?>
<div class="box">
<div class="square menu" style="background: #<?php echo $array['colour']; ?>;" onclick="Radi.menuToggle('<?php echo $array['id']; ?>');">
<img id="menutoggle_<?php echo $array['id']; ?>" class="menutoggle" src="_img/<?php echo ( $array['id'] != $array3['usergroup'] ) ? 'plus' : 'minus'; ?>_white.png" alt="Toggle" align="right" />
<strong><?php echo $array['name']; ?></strong>
</div>
<div class="menuitems"<?php if ($array['id'] != $array3['usergroup']) { ?> style="display: none;"<?php } ?> id="mitems_<?php echo $array['id']; ?>">
<?php
$query2 = $db->query("SELECT * FROM menu WHERE usergroup = '{$array['id']}' ORDER BY weight ASC");
$i = "a";
while ($array2 = $db->assoc($query2)) {
?>
<a href="<?php echo $array2['url']; ?>" class="<?php echo $i; ?>">
<?php echo $array2['text']; ?>
</a>
<?php
$i++;
if ($i == "c") {
$i = "a";
}
}
?>
</div>
</div>
<?php
}
}
?>
</div>
So any ideas on why my code is not doing it?
