CSS Question

Content inside a div in a new column on overflow

I don't find a way to have a vertical alignment of div which wrap to a second column on overflow...

I have a div with a fixed height, inside I have a dynamicaly variable number of texts each wrapped in a div with a fixed width.

I want to display texts in vertical alignment. If there is not enough space, a second column shall be used.
I tried with float and display: inline-block but the element are not below each other.

I think it will be easier to understand with a picture:


A pure CSS solution will be the best!

Here are the base html code of the problem:

<div class="container" style="height: 70px; background-color: lightblue;">
<div style="width: 100px;">Alsace</div>
<div style="width: 100px;">Bretagne</div>
<div style="width: 100px;">Centre</div>
<div style="width: 100px;">Lorraine</div>
<div style="width: 100px;">Picardie</div>

Context: on the left of the main div, I have a country map with different county which can be selected, when a county is selected I want to display it's name close to the map. That's why I want the texts the closest to the left side.

Even better method:

.container {
    display: flex;
    flex-flow: column wrap;

Thanks to @Roberrrt

This can be done with display: flex;

You set the wrapper height to 'item height' x 'vertical item count'.

.container {
  display: flex;
  flex-direction: column;
  align-content: flex-start;
  flex-wrap: wrap;
  height: 250px;/* 5 items x 50px = 250px*/
.container div {
  height: 50px;
  width: 100px;
  background: red;
