That’s it. Here is a screenshot for better view.

<script type="text/javascript">
$(function () {
    $('.checkall').click(function () {
        $('.chk').attr('checked', this.checked);
    });
});
</script>

The html:

<input type="checkbox" class="checkall"/>
<input type="checkbox" value="1" class="chk"/>
<input type="checkbox" value="2" class="chk"/>
<input type="checkbox" value="3" class="chk"/>
<input type="checkbox" value="4" class="chk"/>

$cats = get_categories("child_of=1");

So you can use this code instead:

$parent = 1;// your category parent ID
$where = "AND tt.parent = '$parent'";
$in_taxonomies = "'category'";
$orderby = 't.name';
$order = 'ASC';
$limit = 'LIMIT 0,1000';
$query = "SELECT t.name FROM $wpdb->terms AS t INNER JOIN
    $wpdb->term_taxonomy AS tt ON t.term_id = tt.term_id
    WHERE tt.taxonomy IN ($in_taxonomies) $where ORDER BY $orderby $order $limit";
$categories = $wpdb->get_results($query);

function addFirstLastClass($pageList) {

 // pattern to focus on just lis
 $allLisPattern = '/<li(.*)<\/li>/s';
 preg_match($allLisPattern,$pageList,$allLis);
 $liClassPattern =  "/<li[^>]+class=\"([^\"]+)/i";

 // first let's break out each li
 $liArray = explode("\n", $allLis[0]);

 // count to get last li
 $liArrayCount = count($liArray);

 preg_match($liClassPattern, $liArray[0], $firstMatch);
 $newFirstLi = str_replace($firstMatch[1], $firstMatch[1] . " first-menu-item", $liArray[0]);

 if($liArrayCount > 1){
 $lastLiPosition = $liArrayCount - 1;

 preg_match($liClassPattern, $liArray[$lastLiPosition], $lastMatch);
 $newFirstLi = str_replace($firstMatch[1], $firstMatch[1] . " first-menu-item", $liArray[0]);
 $newLastLi = str_replace($lastMatch[1], $lastMatch[1] . " last-menu-item", $liArray[$lastLiPosition]);
 }

 // replace first and last of the li array with new lis
 // rebuild newPageList
 // set first li
 $newPageList = $newFirstLi . '';
 $i = 1;
 while ($i < $lastLiPosition) {
 $newPageList .= $liArray[$i];
 $i++;
 }
 // set last li
 $newPageList .= $newLastLi;

 // lastly, replace old list with new list
 $pageList = str_replace($allLis[0], $newPageList, $pageList);
 return $pageList;
}
add_filter('wp_nav_menu', 'addFirstLastClass');
