Mosaic Flow

Pinterest like responsive image or HTML grid for jQuery that doesn’t suck. See live example.

Features

• Simple and easy to install.
• Responsive (shows as many columns as needed).
• Very fast.
• Only 1.5 KB (minified gzipped).
• You can use bare <img> tags or arbitrary HTML.

Installation

Include jQuery and jquery.mosaicflow.min.js onto your page:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="jquery.mosaicflow.min.js"></script>

Add some CSS for column layout and to make your content responsive:

.mosaicflow__column {
  float: left;
}
.mosaicflow__item img {
  display: block;
  width: 100%;
  height: auto;
}

Add .mosaicflow CSS class to your content’s contaier:

<div class="clearfix mosaicflow">
  <div class="mosaicflow__item">
    <img src="1.jpg" width="500" height="300" alt="">
  </div>
  <div class="mosaicflow__item">
    <img src="2.jpg" width="500" height="500" alt="">
  </div>
  …
</div>

Image sizes should be specified in HTML in conjunction with option itemHeightCalculation = 'attribute' for even a better performance.

You can also use custom HTML as items:

<div class="clearfix mosaicflow">
  <div class="mosaicflow__item">
    <h4>Lorem ipsum dolor sit amet</h4>
    <p>Excepteur sint occaecat cupidatat non proident</p>
  </div>
  <div class="mosaicflow__item">
    <h4>Lorem ipsum dolor sit amet</h4>
    <p>Excepteur sint occaecat cupidatat non proident</p>
  </div>
  …
</div>

Configuration and manual initialization

You can define options via HTML data attributes or via JavaScript object (manual initialization).

<div class="clearfix mosaicflow" data-item-selector=".item" data-min-item-width="300">

$('#mycontainer').mosaicflow({
  itemSelector: '.item',
  minItemWidth: 300
});

Don’t add .mosaicflow class when you manually initialize Mosaic Flow—it will ignore options specified through Javascript.

Note that option names in JavaScript should be in camelCase but in HTML it should be data-attributes-with-dashes.

Options

itemSelector (default: > *)

jQuery selector of content item.

columnClass (default: mosaicflow__column)

CSS class of column element.

minColumns (default: 2)

Minimum number of columns. Especially useful for mobile devices.

minItemWidth (default: 240)

Minimum item (or column) width. Decrease this number if you want more columns, or increase if you want less.

itemHeightCalculation (default: auto)

Method of calculation items’ heights:

• auto—will calculate automatically each item’s height after being placed in a column, so it is smart enough if your items are responsive and height is being modified as width is (which will happen as columns shrink or expand).

• attribute—will try to grab the value placed in height attribute of <img> tags when these are used as items. This is faster than auto because no calculation is done.

Events

mosaicflow-layout

Fire on every layout change: initialization or change number of columns after window resize.

mosaicflow-start / mosaicflow-ready

Fire before / after the mosaicflow init it's work.

mosaicflow-fill / mosaicflow-filled

Fire before / after reorganized columns.

mosaicflow-item-add / mosaicflow-item-added

Fire before / after adding items.

mosaicflow-item-remove / mosaicflow-item-removed

Fire before / after removing items.

Methods

add

Add any html element into next smallest column.

Example:

// Init mosaicflow
var container = $('#mycontainer').mosaicflow();

// Create new html node and append to smallest column
var elm = $('<div>A new added element</div>');
container.mosaicflow('add', elm);

remove

Remove a given element from its column and updates columns height accordingly. It does not removes the node, just detaches it from document. Example:

// Init mosaicflow
var container = $('#mycontainer').mosaicflow();

// Select the desired element to be removed
var elm = $('#item-3');

// Tell mosaicflow to detach element from its column
container.mosaicflow('remove', elm);

// Now you can place detached node in another location or remove it if you don't need it anymore.
elm.remove();
