One of the solutions mentioned in react-jsonschema-form's GitHub was to use oneOf with every combination of selections listed out.
For your case that would look something like (Code Sandbox):
{
type: "object",
properties: {
food_eaten: {
title: "What kinds of food did you eat today?",
type: "array",
uniqueItems: true,
items: {
type: "string",
enum: ["Fruits", "Meats", "Veggies", "Pastries"]
}
}
},
dependencies: {
food_eaten: {
oneOf: [
{
properties: {
food_eaten: {
const: ["Fruits"]
},
fruit_eaten: {
type: "string",
title: "What kind of fruit did you eat?"
}
}
},
{
properties: {
food_eaten: {
const: ["Meats"]
},
meats_eaten: {
type: "string",
title: "What kind of meat did you eat?"
}
}
},
{
properties: {
food_eaten: {
const: ["Veggies"]
},
veggies_eaten: {
type: "string",
title: "What kind of veggies did you eat?"
}
}
},
{
properties: {
food_eaten: {
const: ["Pastries"]
},
pastries_eaten: {
type: "string",
title: "What kind of pastries did you eat?"
}
}
},
{
properties: {
food_eaten: {
const: ["Fruits", "Meats"]
},
fruit_eaten: {
type: "string",
title: "What kind of fruit did you eat?"
},
meats_eaten: {
type: "string",

They do mention that the solution might become simpler after allOf gets implemented (which it is now) so perhaps you might be able to simplify this approach. I would recommend joining the RJSF discord and ask about it there, you may get some advice.
