/**
Form with single input element, two buttons and two states: normal/loading.
Applied as jQuery method to DIV tag (not to form tag!). This is because form can be in loading state when spinner shown.
Editableform is linked with one of input types, e.g. 'text', 'select' etc.

/**
Select2 input. Based on amazing work of Igor Vaynberg https://github.com/ivaynberg/select2.  
Please see [original select2 docs](http://ivaynberg.github.com/select2) for detailed description and options.  
 
You should manually download and include select2 distributive:  

    <link href="select2/select2.css" rel="stylesheet" type="text/css"></link>  
    <script src="select2/select2.js"></script>  
    
To make it **bootstrap-styled** you can use css from [here](https://github.com/t0m/select2-bootstrap-css): 

    <link href="select2-bootstrap.css" rel="stylesheet" type="text/css"></link>    
    
**Note:** currently `autotext` feature does not work for select2 with `ajax` remote source.    
You need initially put both `data-value` and element's text youself:    

    <a href="#" data-type="select2" data-value="1">Text1</a>
    
    
@class select2
@extends abstractinput
@since 1.4.1
@final
@example
<a href="#" id="country" data-type="select2" data-pk="1" data-value="ru" data-url="/post" data-title="Select country"></a>
<script>
$(function(){
    //local source
    $('#country').editable({
        source: [
              {id: 'gb', text: 'Great Britain'},

        select2: {

        }
    });
    //remote source (simple)
    $('#country').editable({
        source: '/getCountries',
        select2: {
            placeholder: 'Select Country',
            minimumInputLength: 1
        }
    });
    //remote source (advanced)
    $('#country').editable({
        select2: {
            placeholder: 'Select Country',
            allowClear: true,

/**
Combodate input - dropdown date and time picker.    
Based on [combodate](http://vitalets.github.com/combodate) plugin (included). To use it you should manually include [momentjs](http://momentjs.com).

    <script src="js/moment.min.js"></script>
   
Allows to input:

* only date
* only time 
* both date and time  

Please note, that format is taken from momentjs and **not compatible** with bootstrap-datepicker / jquery UI datepicker.  
Internally value stored as `momentjs` object.
