🏛 react-columned

A component that, based on container's width, sorts given child nodes into a preferred number of columns.

Install

npm install --save react-columned

Or if you prefer yarn:

yarn add react-columned

Quick Example:

Sort images into columns. Use default columns configuration.

import Columned from "react-columned";

<Columned>
  <img alt="Image 1" src={"https://..."} />
  <img alt="Image 2" src={"https://..."} />
  <img alt="Image 3" src={"https://..."} />
  <img alt="Image 4" src={"https://..."} />
  <img alt="Image 5" src={"https://..."} />
  <img alt="Image 6" src={"https://..."} />
  <img alt="Image 7" src={"https://..."} />
  <img alt="Image 8" src={"https://..."} />
  <img alt="Image 9" src={"https://..."} />
  <img alt="Image 10" src={"https://..."} />
</Columned>;

How it works

The component uses element-resize-detector (which is the only dependency of this package) to get the
container's width. Based on received result, it then sorts the child nodes into a needed number of columns, which are simple inline-block divs.

Props

Prop	Type	Default	Description
children	React.Node	null	Child nodes which are about to be sorted into columns
className	?string	undefined	Class to append on columns container.
columns	{ [string] : number } | number	{ "320": 1, "480": 2, "800": 3, "1366": 4, "1920": 6 }	Number of columns, per container size, eg. { "320": 1, "480": 2, "800": 3, "1366": 4 }. If you need a fixed amount of columns, regardless of the screen size, just pass a number, eg. 4.

The default { "320": 1, "480": 2, "800": 3, "1366": 4, "1920": 6 } translates to the following:

• container <= 320px : 1 column
• 321px <= container <= 480px: 2 columns
• 481px <= container <= 800px: 3 columns
• 801px <= container <= 1366px: 4 columns
• 1367px <= container: 6 columns

Troubleshooting

If you're having visual issues, try applying the following two CSS rules on every child node:

display: 'block'; // Prevents spacing between child nodes in a column. 
width: 100% // Child nodes might be wider than the column, this prevents it.

You can easily do this by setting a class on the <Columned> component. For example, if the child nodes are img elements (using emotion for defining styles):

const columnedStyles = css({
    img: {
        display: "block",
        width: "100%"
    }
});

<Columned className={columnedStyles}>
    (...)
</Columned>
