jquery - bootstrap-select plugin height issue -

i using bootstrap-select jquery plugin whip select-fields shape. quite nice, there 1 problem. input-fields / buttons have 50px height. select-class refers custom btn-select style:

.btn-select {     .button-variant(@gray; white; white);     height: 50px;     .heading-font;     font-weight: 700; } 

this fixes height, bottom margin within form-group wrong when set height "auto", bottom margin ok. did miss? lot.
