Custom input components can enable conditional fields in Sanity.io.

Hey guys, does sanity support “out of the box” conditional based options. What I mean by that is, if you check an item, it reveals other options?

It unfortunately does not. However, it is definitely possible to do that with a custom input component. Some relevant links:

https://www.sanity.io/guides/how-to-make-a-custom-input-component
https://www.sanity.io/docs/custom-input-widgets
There is also this collection of components that's kinda undocumented:

They're very useful for making you custom input match the rest of the studio. The

sanity.json

file there can help you figure out what paths to use in your

import

statements to get those components.

there is also this... a custom recipe for Conditional Fields

i've used it a couple of times to good effect
