Hi,

I would like to know if there is any way to show only pdf files in the <dropupload> window when we click the explorer button and opens the Windows file explorer

This is the fiddle that I used: https://zkfiddle.org/sample/mh6l3f/1-dropupload-and-fileupload

Thank you!

Hello there!

Long story short, the Fileupload#get method has A LOT of overloaded versions. The one you want in order to access the "accept" param which controls the mime types in the browser file explorer is this one:

Fileupload#get(Map<String, Object> params, String message, String title, String accept, int max, int maxsize, boolean alwaysNative, EventListener<UploadEvent> listener) {

see here: https://zkfiddle.org/sample/mh6l3f/7-dropupload-and-fileupload

Also, FYI Mime type declaration is "a hint that the browser will consider" rather than a hard rule. Some browser / OS can disregard it and almost all of them will let the user switch to . type. So you should still validate your file type after upload.
