Are you asking about FileUploader of Dashboard Framework? If yes then FileUploader can upload multiple files

Do you still have any issue with Dashboard's file uploader widget's ability to add multiple files at once?

Actually I have not been sure with my answer from first place so I have forwarded to dev.team for consult. Sorry that I did not get back to you sooner. The confirmation from dev.team is that FileUploader is for single file upload and they do have plan for MultipleFileUpload class.

Again, sorry for the miscommunication. I can confirm the feature to upload multiple files with Dashboard's FileUploader will be released in a few weeks in the next version.

Yes, since the latest version of Dashboard which is 4.5.0, you can enable Dashboard's FileUploader multiple upload using multiple property when using it:

class InputsBoard extends Dashboard
{
    protected function content()
    {
        return [
            Row::create([
                [ 
                    FileUploaderDemo::create()
                    ->multiple(true);
                ],
            ],
        ];
    }
}

or when initing:

class FileUploaderDemo extends \koolreport\dashboard\inputs\FileUploader
{
    function onInit() 
    {
        $this->multiple(true);
    }
}

To update on this Dashboard's FileUploader multiple upload, we missed the FileUploader views in Amazing and Appstack theme, which include multiple mode. Thus, pls update to the latest KoolReport Pro version 6.3.1 for the feature to work. We are sorry for any inconvenience.
