}
```

## Events

```javascript
iconPicker.on('select', instance => {
    console.log('Select:', instance);
});
```

## Methods

After we initialize IconPicker, we have access instance. Let's look list all available methods:

| Method                    | Description                                                                  |

| `off()`                   | Remove event handler                                                         |

| `hide()`                  | Remove IconPicker's modal                                                    |
| `clear()`                 | Clear current icon                                                           |
| `isOpen()`                | Check if open or not                                                         |

| `destroy(deleteInstance)` | Set it to false (by default it is true) to not to delete IconPicker instance |

## Icon format setting in JSON files

While this picker uses icon sets found at [Iconify](https://github.com/iconify/icon-sets/tree/master/json), it supports
an extension to their format to allow improved performance with large icon sets.

By default, those icon sets include the actual SVG directly, and the picker includes the SVG markup inline. In cases
where the actual SVGs are not needed (e.g. if you're using Font Awesome and the required CSS / JavaScript is
included on the page), adding a new, optional `iconFormat` setting to the JSON file will allow you to remove the SVGs
and reduce file sizes by over 90%, making the loading of the picker much faster.

`iconFormat` is optional and can be set to three different values:

- `svg` (the default) - `body` must include the full SVG.

- `i` - `body` is not needed at all. The picker will use markup like `<i class='far fa-abacus'></i>`.

Example JSON (snipped, `iconFormat` can be set to "i", `body` can be empty or missing entirely)
```json
{
  "prefix": "far fa-",
  "iconFormat": "i",
  "info": {
    "name": "Font Awesome Regular"
  },
  "lastModified": 1689174287,
  "icons": {
    "abacus": {
      "body": "",
      "width": 576
    },
    "acorn": {
      "width": 448
    }
  }
}
```

- `markup` - The picker uses the actual markup set in the `body`. This allows the use of different, custom markup for
icons, e.g. `<span class='far fa-abacus'></span>`.

Example JSON (snipped, `iconFormat` must be set to "markup", `body` must be set)
```json
{
  "prefix": "far fa-",
  "iconFormat": "markup",
  "info": {
    "name": "Font Awesome Regular"
  },
  "lastModified": 1689174287,
  "icons": {
    "abacus": {
      "body": "<span class='far fa-abacus'></span>",
      "width": 576
    }
  }
}
```

To take advantage of this, you could download the JSON file and use search-and-replace to remove the body values from
the file. Then, you would need to set `iconSource` per the Options section above to use your new JSON file.
