i need to put an active class on the <li>
so the that when you are in a team_category it would display <li class="active">
<?php
$sport = get_terms( 'team_category' );
if($sport){
?><ul><?php
foreach($sport as $s){ ?>
<li><a href="<?php echo get_term_link( $s->slug, 'team_category' ) ?>"><?php echo $s->name; ?></a></li>
<?php }
?></ul><?php
}
?>
Something like this should work.
<?php $sport = get_terms( 'team_category' ); ?>
<?php if($sport): ?>
<ul>
<?php foreach($sport as $s): ?>
<li class="<?php if($current_team == $s): ?>active<?php endif; ?>">
<a href="<?php echo get_term_link( $s->slug, 'team_category' ) ?>"><?php echo $s->name; ?></a>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
