css flex-wrap, but vertically?

5 children elements

equal widths
varying heights

I would like to do EXACTLY what flex wrap row does, but VERTICALLY.

.container {
  display: flex;
  flex-wrap: wrap;
  flex-direction: column;
  gap: 5px;
  border: 2px solid #000;
  padding: 10px;
}

.box {
  width: 80px;
  height: 50px;
  background-color: orange;
}

<div class="container">
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
  <div class="box"></div>
</div>

i would basically like to transpose the direction/axis of the wrap (so the wrap would go to the next column, when it reaches the vertical maximum of the parent container.)

all the vertical/column flexings don't create more than one column (wrap over to the next column)

image of what im talking about:

I have tried every combination/permutation of the flex styling params (for both the parent & children)

thanks!

Solution

To make a column flexbox wrap you need to limit the height, just like you limit the width when you want a row flexbox to wrap:

:root {
  --box-width: 80px;
  --box-height: 50px;
  --gap: 5px;
  --col-items: 5;
}

.container {
  display: flex;
  flex-wrap: wrap;
  flex-direction: column;
  gap: var(--gap);
  width: 200px;
  height: calc(
    var(--col-items) * var(--box-height) + 
    (var(--col-items) - 1) * var(--gap)
  );
  border: 2px solid #000;
  padding: 10px;
}

.box {
  width: var(--box-width);
  height: var(--box-height);
  background-color: orange;
}

<div class="container">
  <div class="box">1</div>
  <div class="box">2</div>
  <div class="box">3</div>
  <div class="box">4</div>
  <div class="box">5</div>
  <div class="box">6</div>
  <div class="box">7</div>
  <div class="box">8</div>
</div>

Another option is to use CSS columns that will balance the number of items in each column:

:root {
  --box-width: 80px;
  --box-height: 50px;
  --gap: 5px;
}

.container {
  column-width: var(--box-width);
  column-gap: var(--gap);
  width: 200px;
  border: 2px solid #000;
  padding: 10px;
}

.box {
  width: var(--box-width);
  height: var(--box-height);
  background-color: orange;
  margin-bottom: var(--gap);
}

<div class="container">
  <div class="box">1</div>
  <div class="box">2</div>
  <div class="box">3</div>
  <div class="box">4</div>
  <div class="box">5</div>
  <div class="box">6</div>
  <div class="box">7</div>
  <div class="box">8</div>
</div>
