Consider the following.

 $(function() { function moveChecked(source, target) { var items = $(".card", source).filter(function(index) { return $("input", this).is(":checked"); }); items.css({ top: "", left: "" }).appendTo(target); $("input", items).prop("checked", false); } $(".card").draggable({ revert: "invalid", opacity: .5 }); $("#card-list").droppable({ accept: ".card", drop: function(event, ui) { moveChecked($(".row > .d-flex"), this); } }); });

 .card { width: 80px; height: 80px; color: #fff; } .right-list { background-color: #B91646 !important; } .left-list { background-color: #1F1D36 !important; } .form-check-input { position: absolute; top: 0 !important; right: 0 !important; left: 0 !important; bottom: 0 !important; margin: auto !important; }

First, you cannot use accept in the way you attempted. Draggable should be initialized on it's own.

I created a function yet you can do all this in the drop call back if you like. The function basically knows to look for Checked items and move those from the Source to the Target. It then removes any Drag styling and unchecks the items.

If you like, you can use helper to build an item that reflects all the checked items.

Update

 $(function() { function hideChecked(target) { var items = $(".card", target).filter(function(index) { return $("input.form-check-input", this).is(":checked"); }); items.fadeOut("fast"); } function moveChecked(source, target) { var items = $(".card", source).filter(function(index) { return $("input", this).is(":checked"); }); items.css({ top: "", left: "" }).appendTo(target); $("input", items).prop("checked", false); items.show(); } function makeHelper(event) { var helper = $("<div>", { class: "helper" }); var count = $("#check-list input:checked").length; for (var i = 0; i < count; i++) { var offsetPos = "left+" + (i * 10) + " top+" + (i * 10); $("<div>", { class: "card left-list" }).html("&nbsp;").appendTo(helper).position({ my: offsetPos, at: "left top", of: helper }); } $(".card:last", helper).append("<input class='form-check-input' type='checkbox' checked />"); return helper.get(0); } $("#check-list .card").draggable({ appendTo: ".row", revert: function(dragObj) { if (dragObj === false) { $("#check-list .card").show(); return true; } else { return false; } }, opacity: .5, helper: makeHelper, start: function(event, ui) { hideChecked($("#check-list")); } }); $("#card-list").droppable({ accept: ".card", drop: function(event, ui) { moveChecked($(".row > .d-flex"), this); } }); });

 .card { width: 80px; height: 80px; color: #fff; } .right-list { background-color: #B91646 !important; } .left-list { background-color: #1F1D36 !important; } .form-check-input { position: absolute; top: 0 !important; right: 0 !important; left: 0 !important; bottom: 0 !important; margin: auto !important; } .helper { position: relative; } .helper .card { position: absolute; }
