The column flex-direction property seems to be malfunctioning

Question

The column flex-direction property seems to be malfunctioning

Can anyone help me with styling a ul tag using display: flex? I'm trying to order it by column with flex-direction: column;, but for some reason, it's not working.

Here is the CSS code for the container:

#nav li.four_columns ul.sub-menu {
  width: 600px;
  display: flex;
  -webkit-flex-direction: column;
  flex-direction: column;
  justify-content: flex-start;
  align-items: flex-start;
  flex-flow: wrap;
}

And here is the CSS code for the child elements:

#nav li.four_columns ul.sub-menu li {
  flex-basis: 25%;
  /* white-space: nowrap; */
  /* overflow: hidden; */
  /* text-overflow: ellipsis; */
  /* border-bottom: none; */
}

Identifying the root cause of your issue: flex-flow: wrap

flex-flow: wrap is a compact way of setting values for both flex-direction and flex-wrap.

The default settings for this property are row nowrap.

In your code, you've only specified the flex-wrap part as: wrap.

This indicates that the flex-direction remains at its default value: row.

As a result, your flex items are being aligned horizontally in a wrapping row.

To rectify this, consider defining both components:

flex-flow: column wrap

Alternatively, if you're already using flex-direction: column, remove flex-flow entirely and go with:

flex-wrap: wrap

Note: To ensure flex items wrap in a column, provide a specific height for the container. Without a fixed height, the items won't have guidance on where to wrap, thus expanding the container indefinitely in a single column layout.

If the flex direction in a column layout is not functioning correctly, double-check to ensure that you have specified the height property:

For instance:

#container {
    display: flex;
    width: 100%;
    height: 100%;
    flex-direction: column;
}

.child {
    width: 200px;
    /* height: 200px;*/
    flex: 1;
}

#child1 {
    background-color: red;
    flex: 2;
}

#child2 {
    background-color: green;
}

#child3 {
    background-color: blue;
}

<section id="container">
    <div id="child1" class="child"></div>
    <div id="child2" class="child"></div>
    <div id="child3" class="child"></div>
</section>

For instance:

#container {
    display: flex;
    width: 100%;
    height: 100%;

.child {
    width: 200px;
    /* height: 200px;*/
    flex: 1;
}

#child1 {
    background-color: red;
    flex: 2;
}

#child2 {
    background-color: green;
}

#child3 {
    background-color: blue;
}

<section id="container">
    <div id="child1" class="child"></div>
    <div id="child2" class="child"></div>
    <div id="child3" class="child"></div>
</section>
