<script>
	$('.gereedschap-spec button').click(function() {

		var classname = $('button').parent().attr('class');
		var valuname = $('button').val();

		if ($('#filter-menu > div').hasClass(classname)) {
			$('#filter-menu :checkbox')
				.val(valuname)
				.prop('checked', 'checked')
				.trigger('change');
		}
	});
