PHP - Dropdown Menu Php

So i have a <drop down> menu, and a <nav> menu on my left side of the page. I have a problem when i click at the first column of my drop down menu and it explores submenu, the submenu mixes with the nav menu that is under the drop down menu on the left. i could solve it with margin-top of the nav menu but i don't like the empty space beetwen them. I tried with putting overflow:visible; in CSS of my dropdown menu but it is still the same. drop down menu is seen but there is stil seen nav menu under and they are mixed. So basicly i want my dropdown menu to be priority,  so when i clicks on my first column (only first column is problem because there under is nav menu the other are open nice) it will explore submenu and the part of nav menu that covers the submenu will be hidden.   Here is the screen shot:     Here is the code of head <dropdown> menu if someone finds the problem.

Hi i have a online/offline script that works great no issues at all. In order to change the html, php file to display when offline I need to point it to that file via input field. What i would like is to change the input filed and have a dropdown that list all the folders and subfolders within the the directory where all the templates are located. I have found a php snippet on the forum that does exactly what i want. The issue is now is to remove the input filed in the script and insert the snippet found here and thats where the issue comes. I'm hoping some guru here can easily help me out . please see below for the code

online/offline code ( input filed i would like to replace with dropdown selector <input type="text" name="txttemplate" value="%s" id="txttemplate" />)

thank you

I think after a lot of trouble I've finally managed to get my hierarchical php driven hierarchical dropdown menu working. I now have 1 problem with it which I simply can't figure out. Rather than explain this I think a picture is worth a thousand words so here's the script in action:-

http://www.coolvisiontest.com/garyssite/rhrvouchers/menu4.php

If you notice in that example when you hover over categories then level1a then level2a the menu's and their children appear 1 at a time as they should. However if you hover over level1a then level2b then all at once all of the child categories of 2b and all of their child catagories and their child categories etc appear at once rather than one at a time. You should have to hover over level3e to see level4a and you should have to hover over level4a to see level5a etc.

The code I have is a combination of 2 sets of code I came across to be honest so I'm having trouble figuring it out.


At the moment I only have 3 problems with it:-

1. I only want subcategories to be shown when their parent category is hovered over as explained above
2. I only want the bottom level of categories to act as links e.g. levels 2c 3a 3b 3c 3d and 5a would act as links in this example as they are the last of all the children, the rest of the categories should be plain text. I'm not sure if this is achievable though as I think links are required for the hover functionality.
3. I want some way of indicating to the user that a category has children perhaps by including a little right arrow or plus sign and of course this should only be included for the categories that have children and not the others.

Can anyone help me out with these three things please? Here's my code so far:-



<?php

$link = mysqli_connect('localhost','','');
mysqli_select_db($link,'');

$query = mysqli_query($link,'SELECT * FROM nested_categories');
while ( $row = mysqli_fetch_assoc($query) ){        
$menu_array[$row['id']] = array('id' => $row['id'],'name' => $row['name'],'parent' => $row['parent_id']);
}

function generate_menu($parent){        
$has_childs = false;        

global $menu_array;        

foreach($menu_array as $key => $value){                
if ($value['parent'] == $parent){ 
                              
if ($has_childs === false){                                

$has_childs = true;                                
echo '<ul>';                        
}                        

echo '<li><a href="menu4.php?id='.$value['id'].'">'.$value['name'].'</a>';                        
generate_menu($key);                        

echo '</li>';                
}        
}        
if ($has_childs === true) echo '</ul>';
}

?>

<div id="menu">
<ul>

<li><h2>categories</h2>

<?php generate_menu(0); ?>

</li>

</ul>

</div>




And the Css:-


#menu {
width: 100%;
background: #eee;
float: left;
}
#menu ul {
list-style: none;
margin: 0;
padding: 0;
width: 12em;
float: left;
}


#menu a, #menu h2 {
font: bold 11px/16px arial, helvetica, sans-serif;
display: block;
border-width: 1px;
border-style: solid;
border-color: #ccc #888 #555 #bbb;
margin: 0;
padding: 2px 3px;
}

#menu h2 {
color: #fff;
background: #000;
text-transform: uppercase;
}

#menu a {
color: #000;
background: #efefef;
text-decoration: none;
}

#menu a:hover {
color: #a00;
background: #fff;
}



#menu li {position: relative;}

#menu ul ul {
position: absolute;
z-index: 500;
}

#menu ul ul ul {
top: 0;
left: 100%;
}




div#menu ul ul,
div#menu ul li:hover ul ul,
div#menu ul ul li:hover ul ul
{display: none;}

div#menu ul li:hover ul,
div#menu ul ul li:hover ul,
div#menu ul ul ul li:hover ul
{display: block;}

Hello,   I'm new to php, I don't really have much experience, just have used it in combination with dreamweaver. I'm tackling a new problem now.   Basically, it's about a dropdown menu with pre-defined values. There are multiple dropdowns, having different value choices. People are supposed to be able to select more than one option and then search for the results. these should then be generated according to the selected values, or if no value is selected, ALL is shown.   When the user clicks on search, the values create a msql query that will then be executed and the results shown on the page.   I've been searching high and low for code ideas, but see different stuff everywhere I look, and none of the code seems to be what i want. Some people are using Javascript, some Ajax, or PHP. ideally, I want to use just php and sql   Can someone point me in the right direction on how to tackle this problem, or maybe someone has some code ideas?   Thanks in advance.   Mio
