Height select 2 in bootstrap 3.3.4

select2-bootstrap3.css

/**
* Change three lines
*
/* line 11 */
.select2-container .select2-selection--single {
    box-sizing: border-box;
    cursor: pointer;
    display: block;
    height: 34px;
    user-select: none;
    -webkit-user-select: none; }

/* line 131 */
.select2-container--default .select2-selection--single .select2-selection__rendered {
    color: #444;
    line-height: 32px; }
    
/* line 139 */
.select2-container--default .select2-selection--single .select2-selection__arrow {
    height: 32px;
    position: absolute;
    top: 1px;
    right: 1px;
    width: 20px; }

Thks @ryanpcmcquen, and add below css to move down arrow

.select2-selection__arrow {
    height: 34px !important;
}

super cool and lovely especially when add @vingorius to @ryanpcmcquen solution thanks to you both

But what if I need to create more than one select2 element, and I want each of then with different heigth sizes?
It would be great to have the opportunity to choose the heigth, specially if I'm creating an dynamical element with select2

@ryanpcmcquen @vingorius combining both solutions, it works smoothly..thanks

I find that this works reasonably well (in your own stylesheet):

/* Make Select2 boxes match Bootstrap3 heights: */
.select2-selection__rendered {
  line-height: 32px !important;
}

.select2-selection {
  height: 34px !important;
}

@ryanpcmcquen thanks allot
