JavaScript On-click open list

Question

I have this code below that consists of a list of fruits with a show more button. What i'm currently trying to accomplish is to make a button with a onclick functions that opens the list when i click it.

I am able to achieve that with my current code but the problem i don't want my list to close when i click the button again i only want it to stay open even after i click it again. Is there a easy way to fix this problem any help would be greatly appreciated thanks.

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


var key = "Red Fruits";

So just add a condition in your opening() function that says if the list is closed yet (what mean the link shows "Show More") click the button, like :

function opening() {
    var openList = $('[data-target="#openly"]');

    if (openList.text() === "Show More") {
       openList.click();
    }
}

This way you could control the call of the click event

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) {
    combineString += ('<div class="pilldiv greenpill class">' + greenpill[key2][index] + '</div>');
  });
  $('.combineclass').html(combineString);

  var randomString = '';
  $.each(randompill[key3], function(index) {
    randomString += ('<div class="pilldiv randompill class">' + randompill[key3][index] + '</div>');
  });
  $('.randomclass').html(randomString);
}

function adjustHeight() {
  defHeight = $('#leftpanel').height()
  $wrap.animate({
    height: defHeight
  }, "normal");
}

function listener() {
  $(document).ready(function() {
    $(document).on("click", "#suggestid div", function() {
      data = this.innerHTML;
      $(".total_count_Green_Fruits").html(key2 + ': ' + greenpill[key2].length);
      var element = $(this).detach();
      $('#currentid').prepend('<div class="new-green-fruit pilldiv class ">' + element.html() + '</div>');

      adjustHeight()

    });
  });

  $('body').on('click', 'div.new-green-fruit', function(e) {
    data2 = this.innerHTML;
    $(this).detach();
    var element2 = $(this).detach();
    $('#suggestid').prepend('<div class="pilldiv randompill class" >' + element2.html() + '</div>');

    adjustHeight()

  });
}
redraw();
listener();

var slideHeight = 100;
var defHeight
var $wrap
$(".container").each(function() {
  var $this = $(this);
  $wrap = $this.children(".wrapper");
  defHeight = $wrap.height();
  if (defHeight >= slideHeight) {
    var $readMore = $this.find(".read-more");
    $wrap.css("height", slideHeight + "px");
    $readMore.append("<a data-target='#openly' href='#'>Show More</a>");

    $readMore.children("a").bind("click", function(event) {
      var curHeight = $wrap.height();
      if (curHeight == slideHeight) {
