How to simulate multi-select field in form request?

I’m testing my Laravel backend API and need to send an array of values in the genre field but Postman shows file and text options only.

You need to include a screen shot of your request, and how you are sending the parameters. (For example. as query params, or a JSON body?).

The advice when the issue is directly related to a specific API is to read the documentation for that API. Good documentation will include examples of the requests\calls that should show you the format needed.
