Read the $_GET['option'] from the URL parameter, and tell PHP what the array is going to use.
<?php
if( isset($_GET["option"]) ){
$option = $_GET["option"];
switch ($option){
case "schaatsen":
$child = $evenementen["schaatsen"];
break;
case "alpineskieen":
$child = $evenementen["alpineskieen"];
break;
case "snowboarden":
$child = $evenementen["snowboarden"];
break;
case "ijshockey":
$child = $evenementen["ijshockey"];
break;
case "rodelen":
$child = $evenementen["rodelen"];
break;
}
} ?>
<select name="child-option">
<?php foreach ($child as $item) { ?>
<option><?php $item ?></option>
<?php } ?>
</select>
Use foreach( $child as $item ) for each option.
