Display list view control items vertically instead of horizontally

there is no such OOTB functionality.

you could try to play with CSS to rotate it, but the result is not very usable.

I tried with following CSS, if you want to play on your own

.myViewCtrl table.ms-listviewtable{
    transform:rotate(-90deg); 
    border: 1px solid black !important; 
    border-collapse: collapse !important;  
}

.myViewCtrl table.ms-listviewtable th {
    transform:rotate(90deg);
    border: 1px solid black !important; 
    border-collapse: collapse !important;  
}

.myViewCtrl table.ms-listviewtable td {
    transform:rotate(90deg);
    height: 50px !important;
    width: 200px !important;
    border: 1px solid black !important; 
    border-collapse: collapse !important;  
}

Thanks.  For now, I'll just leave it as it is.  It actually functions fine.  I may try this for future attempts.
