Fɔ ansa

Dis Sass loops nor de limited to kala map, tu. Yu kin jεnarεt rεspכns vεryushכn dεm bak fכ yu kכmכpכnt dεm. Tek fɔ ɛgzampul wi rispɔnsiv alaynɛshɔn fɔ di drɔpdɔwn dɛn usay wi miks wan @eachlɔp fɔ di $grid-breakpointsSass map wit wan midia kwɛstyɔn inklud.

// We deliberately hardcode the `bs-` prefix because we check
// this custom property in JS to determine Popper's positioning

@each $breakpoint in map-keys($grid-breakpoints) {
  @include media-breakpoint-up($breakpoint) {
    $infix: breakpoint-infix($breakpoint, $grid-breakpoints);

    .dropdown-menu#{$infix}-start {
      --bs-position: start;

      &[data-bs-popper] {
