The current behavior :
/users?hobbies=handball&hobbies=volley
A Solution :
<form action="/users" method="POST">
<select class="form-control" name="hobbies[]">
<option value="" selected disabled>Select Users</option>
<option value="bread">Best bread available</option>
</select>
</form>
Will generate a URL /users?hobbies[]=bread&name
In Laravel PHP, it will automatically create an array variable.
