Use a select option as variable further down the same form in laravel

I try to get the selected option for the Team select on my form to further use it in the same form to limit the available positions in the selected team.
I managed to limit each team, so that it has a maximum of 9 players.
The idea is to have +-2 players on each position( 2 forward, 2 center, 2 back, 3 substitutes) for each team, if the spots are full the 'position' (ex. forward) option doesn't show up for the selected team.
Might be helpful : I am using foreign keys : (player -> one position_id, team -> many players)
My positions table is consisted of id, name and max and it is passed as $positions
I am trying to figure out a way, i am new to the subject so if you guys can help me, would be a great.
Or tell me if it isn't possible.

Thanks in advance.

 <form action="/player" method="POST" enctype="multipart/form-data" class="form-control">
