                $("#parent").find('.room-sheet').children().eq(i).remove();

  })
</script>

Listen for clicks on a .sday on the parent, navigate to the parent of the clicked .sday (a .room-sheet ), call nextAll to get all subsequent siblings, and .remove() them:

 $('#parent').on('click', '.sday', function() { $(this).parent().nextAll().remove(); }) 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div id="parent" class="parent"> <div class="room-sheet"> <div class="sday">1</div> </div> <div class="room-sheet"> <div class="sday">2</div> </div> <div class="room-sheet"> <div class="sday">3</div> </div> <div class="room-sheet"> <div class="sday">4</div> </div> </div> 

Also, there's no need to require a big library like jQuery for something this simple, you may implement this with native DOM methods, if you like:

 document.querySelector('#parent').addEventListener('click', ({ target }) => { if (!target.matches('.sday')) { return; } const sheet = target.parentElement; while (sheet.nextSibling) { sheet.nextSibling.remove(); } }); 

 <div id="parent" class="parent"> <div class="room-sheet"> <div class="sday">1</div> </div> <div class="room-sheet"> <div class="sday">2</div> </div> <div class="room-sheet"> <div class="sday">3</div> </div> <div class="room-sheet"> <div class="sday">4</div> </div> </div>

Save the current number and the maximum number in variables then just iterate through them, making sure not to delete the clicked one:

$(".sday").on("click", function() {
  let start = parseInt($(this).text());
  let finish = parseInt($(".sday").last().text());
  for (let i = start + 1; i <= finish; i++) {
    $(`.sday:conatins(${i})`).remove();
  }
});
