**CDNJS**

The folks at CDNJS host a copy of the library. The CDN is updated after the release is made public, which means there is a delay between the publishing of a release and its availability on the CDN, so keep that in mind. Just use these links:

## Forking
If you find that you need a feature that SumoSelect does not currently support, either let me know via the SumoSelect issue tracker, or fork SumoSelect on Github and easily extend SumoSelect to create your own widget!

## Usage

*To just go with the default options simply do*

```javascript
$(document).ready(function () {
  $('.selectBox').SumoSelect();
});
```

*To provide optional settings, simply pass a settings object to SumoSelect()*

```javascript
$(document).ready(function () {
  $('.selectBox').SumoSelect({
    placeholder: 'This is a placeholder',
    csvDispCount: 3
  });
});
```

*You can also use data attributes to set options*

```html
<select class="selectBox" multiple data-max="2">
```

If you want an instance to the SumoSelect object to call handler methods

```javascript
const select;
$(document).ready(function () {
  select = $('.selectBox').SumoSelect();
});
```
*NOTE: SumoSelect returns an array of select elements if there are more than one in the matching selector.*

You can also find the instance to the SumoSelect object by directly selecting your select element like
```javascript
$('select.selectBox')[0].sumo. .....
```

You can perform all the operations on the underlying original select and then reload the UI by 
```javascript
$('select.selectBox')[0].sumo.reload();
```

##### You can bind your handlers to some sumoselect specific events eg.
```javascript
$('select.selectBox').on('sumo:opened', function(sumo) {
  // Do stuff here
  console.log("Drop down opened", sumo)
});
```
Available events

- `sumo:opened`
- `sumo:opening`
- `sumo:closing`
- `sumo:closed`
- `sumo:initialized`
- `sumo:unloaded`
