Bootstrap 4 select design and buttons

[fklee]

For bootstrap 4 design,

Select elements should have "form-control" class to have bootstrap 4 design. Maybe button could have btn-block to full width design, but not float right.

@fklee you can add this css for full width buttons:
.btn-group.buttons { display: flex; } .buttons .btn { flex: 1; }
It tested by Bootstrap 5.1.3 and work fine.
