mysql php jquery hide show select
<p>I know a little bit of PHP programming, but none of JQuery. 
I have build a <code>&lt;select&gt;</code> dropdown menu with data from MySql db.
But now I want a button or something next to the <code>&lt;select&gt;</code> option, like a + sign or something that will give me a extra <code>&lt;select&gt;</code> option. And that this can come as many time as you want.</p>

<p>Ps. I'm sorry for my English.</p>

<p>Here is a picture of how I want this to be.</p>

<p>and then next you will get this.

And here is the code what I already have made.</p>

<pre><code>&lt;?php

    $conn = new mysqli('localhost', 'username', 'password', 'database') 
    or die ('Cannot connect to db');

    $result = $conn-&gt;query("select id, name from table");

    echo "&lt;html&gt;";
    echo "&lt;body&gt;";
    echo "&lt;select name='id'&gt;";

    while ($row = $result-&gt;fetch_assoc()) {
        unset($id, $name);
        $id = $row['id'];
        $name = $row['name']; 
        echo '&lt;option value="'.$id.'"&gt;'.$name.'&lt;/option&gt;';         
    }

    echo "&lt;/select&gt;";
    echo "&lt;/body&gt;";
    echo "&lt;/html&gt;";
?&gt;
</code></pre>
