<!-- Filters -->
<?php
$has_filters = false;
ob_start();
if( have_rows('portfolio') ): ?>
<div class="row spacer-bottom-sm">
<div class="col">
<ul class="list-labels d-none d-lg-flex">
<?php while( have_rows('portfolio') ): the_row(); ?>
<?php if( have_rows('filters') ): ?>
<li><button class="label active" data-filter="*">Tous</button></li>
<?php while( have_rows('filters') ): the_row();
if (get_sub_field('title')) {
$has_fitlers = true;
$title = get_sub_field( 'title' );
$class = get_sub_field( 'class' );
?>
<li><button class="label" data-filter=".<?php echo $class; ?>"><?php echo $title; ?></button></li>
<?php
} // end if get sub field
?>
<?php endwhile; ?>
<?php endif; ?>
<?php endwhile; ?>
</ul>
</div>
</div>
<?php endif;
$filters = ob_get_clean();
if ($has_filters) {
