How can I adjust the width of an HTML dialog tag to accommodate wrapped content?

CodePen

In my HTML, I have a dialog element filled with content. What I am trying to achieve is for the content to adjust its layout based on the height of the dialog container. If the content exceeds the container's height, it should wrap and create a new column. However, I also have specific limitations on how tall the container can be for aesthetic reasons.

I attempted using flex-flow: column wrap to make the content flow into a new column when needed, but the issue arises because the dialog itself does not resize to fit the content. Is there a way to dynamically expand the dialog tag to accommodate the flowing content?

Answer №1

This particular issue has been identified: Flexbox items wrapping in column mode do not cause container width to grow

In summary, current browsers do not horizontally expand flex containers with the property flex: column wrap set, unlike how they do vertically for flex: row wrap

Answer №2

Include a CSS property called max-height using the vh unit (which represents vertical height, with 100 being the full window height). Check out a demo on CodePen

.country-selector-stylized-dialog .country-selector-container {
  display: flex;
  flex-flow: column wrap;
  height: 10em;
  max-height: 60vh;
}
  <dialog class="country-selector-stylized-dialog" open="">
    <div class="country-selector-container">
      <div class="country-selector-item country-selector-current-item"> Ireland </div>
      <div class="country-selector-item"> Australia </div>
      <div class="country-selector-item"> België </div>
      <div class="country-selector-item"> Brazil </div>
      <div class="country-selector-item"> Canada </div>
      <div class="country-selector-item"> Danmark </div>
      <div class="country-selector-item"> Deutschland </div>
      <div class="country-selector-item"> España </div>
      <div class="country-selector-item"> France </div>
      <div class="country-selector-item"> India </div>
      <div class="country-selector-item"> Italia </div>
      <div class="country-selector-item"> Nederland </div>
      <div class="country-selector-item"> New Zealand </div>
      <div class="country-selector-item"> Norge </div>
      <div class="country-selector-item"> Österreich </div>
      <div class="country-selector-item"> Schweiz </div>
      <div class="country-selector-item"> Singapore </div>
      <div class="country-selector-item"> Suomi </div>
      <div class="country-selector-item"> Sverige </div>
      <div class="country-selector-item"> United Kingdom </div>
