Display list items in 2 columns

Question

if you run a snapshot of the code or [js fiddle https://jsfiddle.net/3xdfwsk7/1/ ], if we click on the 2nd image, you can see apple1 to apple 12 values. but I want to display apple 1 apple 7 in one column and apple 8 to apple 12 in another column.

Now:

what I need:

#narrow-by-list { display :none;}
.choose1 
{ 
text-transform: capitalize; 
text-align: center;
font-weight:bold;
font-size:18px;
color: #000000;
}
.links1234 { color : #908983;}
.links1234:hover { color : #f85700;}


.grow {
  padding: 5px 5px 5px 5px;
  border-radius: 10px;
  width: 23%;
  margin: 5px 1% 5px 1%;
  float: left;
  position: relative;
  transition: height 0.5s;
  -webkit-transition: height 0.5s;
  text-align: center;
  background-color : #fff;
  
}
.grow:hover ul{
  display: block;
}

.grow ul {
  margin: 0;
  padding: 5px;
  list-style: none;
  display: none;
  position: absolute;
  z-index: 1;
  background: #fff;
  box-shadow: 0 0 5px 1px rgba(0,0,0,.25);
  left: 0;
  right: 0;
}

.grow img{
  width: 100%;
}

.expand 
{
	position:relative;
	right:8px;
	top:4px;
}

<div class="grow">

Note . I need to display in 2 columns only if we have more than 7 values, if we hover over the first image, than only 4 values ​​display, because I do not want to display in 4 columns

This question is not duplicated, because when I used a different answer to the question, it messed up my column width ....

Answer 1

css

.grow:hover ul{
  display: block;
  column-count: 2;
}
.grow:hover ul li{
    display: inline-table;
    padding: 5px 12px;
}

Answer 2
