Multiselect drop down

I have a PHP question. I am trying to alter some code that a partner of mine wrote (he has since then left and cannot be contacted) but I am not hugely familiar with PHP. I believe that the question will be fairly simple but I am not sure where to start. Currently there is a drop down menu that allows you to select only one option. I BELIEVE the code that is involved in that process is here: 

<select id='List' style='width:75px' onchange='displayEx(this);'>
    <option value="0">list</option>

    <?php
    foreach ($LIST as $list)
    {
        echo "<option value='$list'>$list</option>";
    }
    echo "</select>";
    ?>   
<select id='selectd' style='width:75px'>
        <option value="0">X</option>
        </select>
        <input id="addTest" type="button" value="Add" onclick="addTest();"/>
        <p id='error_display' style="height:10px;"></p>
        <div>
            <?php
                $i = 1;
                foreach ($Groups as $G)
                {
                echo "<div style='float:left;width:30%;height:100px;display:inline'><p id='Group $i' title='$G'>Group $G:</p><p id='display_Group_$i'>0/94</p><input id=\"get_Group_$i\" type=\"button\" value=\"Create\" onclick=\"createSheet($i);\" disabled = \"true\" style=\" vertical-align:bottom; display:inline;\"/></div>";
                $i++;
                }
            ?>
        </div>

But I am not sure what to do with it. I was thinking something like this...

foreach ($select as $value)  
{  
    echo '<option';  
    if (isset($_POST['select']) && $_POST['select'] == $value)  
    SOMETHING HERE
}

I don't know though. Other peoples code can sometimes be so confusing (particularly in a language you aren't the best at). For my sanity I hope someone can help me puzzle this out but even if someone could help me translate the current code I would be super grateful.

Use multiselect for the select tag 

 <select multiple="multiple">
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>
