just listen bootstraps dropdown events , adjust elements z-index. check snippet, should choose bit more precise selectors did though.

$('.flip').hover(function(){    $(this).find('.card').toggleclass('flipped');  });    $('.btn-group').on('show.bs.dropdown', function () {    $(this).parentsuntil($( ".face", ".back")).css('zindex', 200);  })    $('.btn-group').on('hidden.bs.dropdown', function () {    $(this).parentsuntil($( ".face", ".back")).css('zindex', 0);  })
body{    padding-top:50px;    background: #555;  }  .flip {    -webkit-perspective: 800;  perspective: 800;        position: relative;   text-align: center;  }  .flip .card.flipped {    -webkit-transform: rotatey(-180deg);      transform: rotatey(-180deg);  }  .flip .card {      height: 100%;    -webkit-transform-style: preserve-3d;    -webkit-transition: 0.5s;      transform-style: preserve-3d;      transition: 0.5s;  }  .flip .card .face {      -webkit-backface-visibility: hidden ;      backface-visibility: hidden ;    z-index: 2;       }  .flip .card .front {    position: absolute;     width: 100%;    z-index: 1;    }  .flip .card .back {    -webkit-transform: rotatey(-180deg);      transform: rotatey(-180deg);  }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
