/**
* ## Filemanager Widget
*
* Creates an input field and a button in order to make it possible to upload files or to select already
* uploaded files. This widget checks if the responsive filemanager is present, if it is, the responsive
* filemanager will be used, else a fallback will be used, which is an input field of type 'file'.
*
* ### Options
*
* **Type | `data-filemanager-type` | String | Optional**
*
* Provide the allowed file upload type. Currently there are 3 options which are:
* * 'all' - All file types are allowed
* * 'videos' - Only video files are allowed
* * 'images' - Only images are allowed
* If you don't provide any type, the filemanager will default to 'all'.
*
* **Content Directory | `data-filemanager-content-directory` | String | Required**
*
* Provide the directory which should be opened when the filemanager gets opened, e.g. 'media'.
* You can also provide a path from the root of your shop e.g 'images/slider_images'.
*
* **Name | `data-filemanager-name` | String | Required**
*
* The name of the input field. It will be set as the HTML name attribute.
*
* **Previous File | `data-filemanager-previous-file` | String | Optional**
*
* Name of the previous file. The name will be used in order to auto fill the input field.
*
* **Page | `data-filemanager-page` | String | Optional**
*
* The name of the current page in snake case, for example: new_category or responsive_filemanager.
* This option will be used in order to load custom configuration files for the responsive file manager like
* responsive_filemanager.config.php. These custom configuration files will be available or should be created
* in the 'page' directory of the responsive file manager.
*
* **Page Active | `data-filemanager-page-active` | Boolean | Required**
*
* This option is required in order to check whether the file manager module is active, and if the configuration
* option from the file manager is set to active, for the current page. If the module is not active, or active
* in general but not active for the current page, the fallback will be used, which is a standard input field.
*
* ### Example
*
* ```html
* <div data-gx-widget="filemanager"
* data-filemanager-name="categories_icon" // Required
* data-filemanager-type="images" // Optional
* data-filemanager-content-directory="images/categories/icons" // Required
* data-filemanager-previous-file="filename.extension" // Optional
* data-filemanager-page="responsive_filemanager"> // Optional
* data-filemanager-page-active="true" // Required
* </div>
* ```
*
