Advanced Usage

- The <select> lists are added with JavaScript in <span> elements with class="dslists". This class can be used in CSS to style de <select> items in your web page.
For example:
.dslists select {
 background: #fbfeda;
}

- Each <select> element has name="dslists[]" attribute, that can be used in PHP scripts to get selected value.
If you add the Select-Lists into a <form> that sends data to a PHP script, you can use the "dslists" name to get the values of selected options.
        $_POST['dslists'][0] contains the value of selected option in first select-list, $_POST['dslists'][1] contains the value of selected option in second select-list, and so on.

- The value of each <option> contains the ID of that option and String value you added for that option, separated by "_", for example: value="3_text-string".
If you want to separate the ID and text-string value in PHP script, apply explode() function.
For example, this code separates and outputs the ID and Text value of the options selected in "dslists" items.
if(isset($_POST['dslists'])) {
  $nrdsl = count($_POST['dslists']);     // number of 'dslists' items

  // outputs the ID and String value of each selected option
  for($i=0; $i<nrdsl; $i++) {
    $id_val = explode($_POST['dslists'][$i], 2);       // gets separated ID and text-string

    // $id_val[0] contains the ID, $id_val[1] contains the text-string
    echo '<br/>ID = '. $id_val[0] .' / Text = '. $id_val[1];
  }
