# angular-select2

> [select2](http://ivaynberg.github.io/select2/) bindings for Angular.JS

## Installation
Add angular-select2 to your project:

```
bower install --save angular-select2
```

Add it to your HTML file:

```html
<script src="bower_components/angular-select2/dist/angular-select2.min.js"></script>
```

Reference it as a dependency for your app module:

```js
angular.module('myApp', ['rt.select2']);
```

## Usage
Usage a similar to a normal select with `ngOptions`:

```html
<select2 ng-model="obj.field" s2-options="val.id as val.name for val in values"></select2>
```

*Note: using `ng-options` was supported until Angular 1.4 made this impossible. When upgrading to Angular.JS 1.4, be sure to replace all instances of `ng-options` to `s2-options`.*

In fact, you can replace any `<select>` tag by a `<select2>` tag and it should just work.

A multi-selection works similarly: add a `multiple` attribute.

You can set any [select2](http://ivaynberg.github.io/select2/) option by passing an options object:

```html
<select2 ng-model="obj.field" s2-options="val.id as val.name for val in values" options="{ allowClear: true }"></select2>
```

## Async loading of data
Async-loaded data can by used by leaving out the `s2-options` attribute and by specifying a `query` function:

```js
angular.module('myApp').controller('MyController', function ($scope) {
    $scope.queryOptions = {
        query: function (query) {
            var data = {
                results: [
                    { id: "1", text: "A" },
                    { id: "2", text: "B" }
                ]
            };

            query.callback(data);
        }
    };
});
```

```html
<select2 ng-model="values.query" options="queryOptions"></select2>
```

## Custom formatting, restrictions, tokenization, ...
This directive is just simple glue to the underlying select2.

[Check the select2 documentation for an overview of the full capabilities.](http://ivaynberg.github.io/select2/)

## Configuring global defaults
You can set a default for any option value by using `select2Config`:

```js
angular.module("myApp").run(function (select2Config) {
    select2Config.minimumResultsForSearch = 7;
    select2Config.dropdownAutoWidth = true;
});
```
