The current FileUpload component in Perspective does not support filtering filetypes when opening the filepicker, instead its only value is to select all files
Here's a React example on how to implement this (it is very easy to do) : Simple react hook to open browser file selector
IA Engineers would just need to use the values from the supportedFiletypes prop within something similar to the linked React code
I found a former issue related to this, though that user accepted the status quo rather than suggesting an implementation change. It does, however, point to a problem where the current implementation does not act how end users and integrator expect this component to work, since it caused confusion enough for someone to make a forum post about it.
Anyhow, wishing anyone reading this the best and would appreciate if an IA Engineer could review this feature request. Seeing as it's a small change and is easy to implement and will benefit end users by making it easier to see and select correct files with the FileUpload Perspective component I hope that this change request is excepted and implemented.
Thank you and have a good day!
