AngularJS Packery Directive

An AngularJS directive to work with David Desandro's Packery.

Usage

1. bower install --save angular-packery
2. Add wu.packery to your application's module dependencies.
3. Include dependencies in your HTML.
4. Use the packery directive.

Example

See the homepage for a live example.

<div packery>
    <div class="packery-brick" ng-repeat="brick in bricks">
        <img ng-src="{{ brick.src }}" alt="A packery brick">
    </div>
</div>

You have to include the packery attribute on the element holding the bricks. The bricks are registered at the directive through the packery-brick CSS classname.

The directive uses imagesloaded to determine when all images within the packery-brick have been loaded and adds the loaded CSS class to to the element, so you can add custom styles and prevent ghosting effects.

Attributes

item-selector

(Default: .packery-brick)

You can specify a different item selector through the item-selector attribute. You still need to use packery-brick either as class name or element attribute on sub-elements in order to register it to the directive.

Example:

<packery item-selector=".mybrick">
    <div packery-brick class="mybrick">Unicorns</div>
    <div packery-brick class="mybrick">Sparkles</div>
</packery>

column-width

The column-width attribute allows you to override the the width of a column of a horizontal grid. If not set, Packery will use the outer width of the first element.

Example:

<packery column-width="200">
    <div class="packery-brick">This will be 200px wide max.</div>
</packery>

preserve-order

The preserve-order attributes disables the imagesLoaded logic and will instead display bricks by the order in the DOM instead of by the time they are loaded. Be aware that this can lead to visual glitches if the size of the elements isn't set at the time they are inserted.

Example:

<packery preserve-order>
    <div class="packery-brick"><img src="..." alt="Will always be shown 1st"></div>
    <div class="packery-brick"><img src="..." alt="Will always be shown 2nd"></div>
</packery>

load-images

This attribute defaults to true and allows to disable the use of imagesLoaded altogether, so you don't have to include the dependency if your packery layout doesn't actually make use of images.

Example:

<packery load-images="false">
    <div class="packery-brick"><p>Only text.</p></div>
    <div class="packery-brick"><p>And nothing but text.</p></div>
</packery>

reload-on-show

The reload-on-show attribute triggers a reload when the packery element (or an ancestor element) is shown after being hidden, useful when using ng-show or ng-hide. Without this if the viewport is resized while the packery element is hidden it may not render properly when shown again.

Example:

<packery reload-on-show ng-show="showList">
    <div class="packery-brick">...</div>
    <div class="packery-brick">...</div>
</packery>

When showList changes from falsey to truthy ctrl.reload will be called.

packery-options

You can provide additional options as expression either as packery or packery-options attribute.

Example:

<packery packery-options="{ transitionDuration: '0.4s' }">
</packery>

Equivalent to:

<div packery="{ transitionDuration: '0.4s' }">
</div>
