Context Menu items are added using “Web Integration”
My Web Integration (Context Menu) Configuration is:
Supports all file extensions
Integration Type is “Files”
Everything is working as expected when select a single file and perform the context menu action. However, my context menu option is not visible when I select multiple files.
I do see your point, there should be some sort of option where a developer could declare if it accepts multiple files or not, and if the application is expected to receive a list of file ids or trigger multiple requests.
This is how our product managers gather feedback from customers and they use it to decide on things like road map, and a note form a customer or developer has some weight.
