What is this?

angular-dynamic-layout is an AngularJS dynamic grid layout. It is inspired from the successfull jQuery isotope library and its underlying masonry layout.

Including jQuery isotope into AngularJS directives gets easily hacky, this library reproduces the layout behavior while taking advantage of ngRepeat filtering and ordering as well as ngAnimate module.

It is meant to be a very light and customizable frame leaving a lot of freedom to the user, especially regarding templates, animations and overall design and responsiveness.

This is a beta version and not production-ready.

Demo

Installation

bower install angular-dynamic-layout
```
Or

npm install angular-dynamic-layout

# Usage
Controller:

$scope.cards = [ { template : "app/partials/aboutMe.html", }, { template : "app/partials/businessCard.html", } ];

Template:

````

Cards

Items must have a template property, this template will be dynamically included using the ng-include directive.

Content: the templates' HTML content is entirely up to you.
Controller: each card can have a specific controller, you can also have a common controller for all cards. For example:

<!-- aboutMe.html -->
<div ng-controller="aboutMeController">
  My Card
</div>

External Scope: to reach the directive's parent controller you can use externalScope() in the cards' template.
Data: you can provide any data to your templates from the list of cards, for example:

Contoller:

$scope.cards = [
  {
    template : "app/partials/work1.html",
    tabs : ["home", "work"],
    data : {
      "position" : "Web Developer",
      "company" : "Hacker Inc."
    },
    added : 1414871272105,
  },
  {
    template : "app/partials/work1.html",
    tabs : ["home", "work"],
    data : {
      "position" : "Data Scientist",
      "company" : "Big Data Inc."
    },
    added : 1423871272105,
  }
];

Template:

<div>
  <div>
    <p>Position</p>
    <h4>{{it.data.position}}</h4>
  </div>
  <div>
    <p>Company</p>
    <h4>{{it.data.company}}</h4>
  </div>
</div>

Responsiveness

To make your layout responsive just create a set of media queries that ajust the size of your cards and of the container. dynamic-layout will find the container and cards widths on its own. A layout will be triggered when the screen's size changes.

Animations

The animations are based on the ngAnimate module, they are entirely up to you and set in the CSS. Here are the available animations:

move-items-animation: use this class to animate the movement of the cards between two positions, for example:

.move-items-animation{
  transition-property: left, top;
  transition-duration: 1s;
  transition-timing-function: ease-in-out;
}

ng-enter and ng-leave: you can animate the entering and leaving of your cards in the grid, for example when applying filters:

.dynamic-layout-item-parent.ng-enter{
  transition: .5s ease-in-out;
  opacity:0;
}
.dynamic-layout-item-parent.ng-enter.ng-enter-active{
  opacity:1;
}

.dynamic-layout-item-parent.ng-leave{
  transition: .5s ease-in-out;
  opacity:1;
}
.dynamic-layout-item-parent.ng-leave.ng-leave-active{
  opacity:0;
}

Features

Filtering

You can provide and update a list of filters like this:

<div dynamic-layout items="cards" filters="filters"></div>

Those filters needs to be in the Conjuctive Normal Form. Basically a list of and groups composed of or groups. Each statement contains the property to be evaluated, a comparator and the value(s) allowed. For example:

var filters = [ // an AND goup compose of OR groups
  [ // an OR group compose of statements
    ['color', '=', 'grey'], // A statement
    ['color', '=', 'black']
  ],
  [ // a second OR goup composed of statements
    ['atomicNumber', '<', 3]
  ]
];

The list of comparators available are:

['=', '<', '>', '<=', '>=', '!=', 'in', 'not in', 'contains']

Custom filters

You can make your own filters by providing any function that takes the item as input and returns a boolean. For example:

var myCustomFilter = function(item){
  if(item.color != 'red')
    return true;
  else
    return false;
};

filters = [
  [myCustomFilter]
];

Sorting

You can provide and update a list of rankers like this:

<div dynamic-layout items="cards" rankers="rankers"></div>

Each ranker contains the property to be evaluated and the order. If two items are the same regarding the first ranker, the second one is used to part them, etc.

var rankers = [ 
  ["color", "asc"], 
  ["atomicNumber", "desc"]
];

Custom rankers

You can make your own ranker by providing any function that takes the item as input and returns a value to be evaluated. For example:

var myCustomGetter = function(item){
  if(item.atomicNumber > 5) return 1;
  else return 0;
};

rankers = [
  [myCustomGetter, "asc"]
];

Adding and removing items

You can add or remove any items from the cards list controller and the dynamicLayout directive will detect it. For example:

$scope.cards.splice(index, 1);

Triggering layout and callback

If a card is modified in any way (expanded for example) you can trigger a layout by broacasting in the $rootScope. Once the animations are completed the callback will be executed.

$scope.toggleText = function(){
  $scope.showingMoreText = !$scope.showingMoreText;
  // We need to broacast the layout on the next digest once the text
  // is actually shown
  $timeout(function(){
    $rootScope.$broadcast("layout", function(){
      // The layout animations have completed
    });
  });
}
