Hi Malcolm,
Thanks for contacting Syncfusion support.
Uploading multiple files in a single POST method functionality is not available in EJ UploadBox control. But we have considered this request as a feature for EJ2 Uploader. This feature will be implemented and rolled out any of our upcoming Volume releases.
Currently, we are focused on implementing the new features in EJ2 components based on the feature requests count from the customers.
We will consider implementing any new feature in EJ1 components only after all the planned features in EJ2 components are implemented.
Generally, we will plan the component implementation based on customer request count and wish-list plan.
You can track the status through the below portal link.
Note: We can also integrate both EJ2 & EJ1 components in the same application. Please refer following documentation,
Please, let us know if you like to switch from EJ1 TreeView to EJ2 TreeView components in our application. We will also be happy to provide any required assistance for migration.
Please let us know, if you need any assistance.
Regards,
Muthukrishnan K
