Sending an array of objects as form-data

How can I send an array of objects as form-data?

I send something similar but with raw json like this:
{
“quiz”:[{
“question”: "what is the correct answer of 2 + 2: ",
“type”: 0,
“answer”: [
{
“name”: “2”
},
{
“name”: “3”
},
{
“name”: “5”
},
{
“name”: “4”
},
{
“name”: “10”
}
]
}]
}
The type means the type of the awser i’ll have in my frontend
0 = radio buttons
1 = text fields

I try this in raw but i need to send it in form-data, any ideas?.
