Uploader accept file

It seems that I can only filter files to png/gif/jpg and text. Why it is not possible to filter image/svg or text/bxf2? (bxf2 is an own xml format /ending)

There are two levels of filtering

• onBeforeFileAdd event can be used to define any kind of js logic, https://docs.webix.com/api__ui.uploader_onbeforefileadd_event.html

• accept configuration property, uses native browser functionality
  https://docs.webix.com/api__ui.uploader_accept_config.html

So, in the case of accept we are limited by the browser’s functionality. If you want a full control, use onBeforeFileAdd ( user will be able to select file, but it will not be added to the upload list )
