显示更多/更少切换不会显示全部内容

Question

我下面的代码由2个列表Total Fruits and Random Fruits组成，我能够将值从一个列表移到另一个列表，反之亦然。问题是我添加了Random fruits to Total fruits的所有水果并单击“显示更多”按钮后，它无法显示完整列表。

我不太确定是什么导致了此问题，对您的帮助/建议将不胜感激！

我相信此问题正在发生，因为正在将面板上的固定高度设置为隐藏溢出状态。尝试在overflow: scroll类上设置wrapper，如下面的代码片段所示。

编辑：

当您从overflow完全删除wrapper时，它似乎似乎表现更好

var redpill = {};
var greenpill = {};
var randompill = {};


var key = "Red Fruits";
redpill[key] = ['Apple', 'Cherry', 'Strawberry', 'Pomegranate', 'Rassberry', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew'];

var key2 = "Green Fruits";
greenpill[key2] = ['Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew'];

var key3 = "Random Fruits";
randompill[key3] = ['Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew'];

function redraw() {
  var combineString = '';
  $.each(redpill[key], function(index) {
    combineString += ('<div class="pilldiv redpill class">' + redpill[key][index] + '</div>');
  });
  $('.combineclass').html(combineString);

  $.each(greenpill[key2], function(index) {
