Description

Suppose we defined a field of checkboxes with 4 options(A, B, C, D) and another field will show dependent on its checked options included A option. e.g. we checked (A, B)/(A, C)/(A, B, C)/(A, B, C, D) the other field should be shown in all these cases And no matter the order we checked these options, like for (A, B), we can checked B then A or checked A then B

You can probably do this with a combination of contains and oneOf -- see https://json-schema.org/understanding-json-schema/reference/array.html#contains for more details on contains.

Perhaps, did that work?

Similar use case--it worked for me. Just one small adjustment since contains is supposed to be a schema:

"contains": {
  "const": "A"
}

Playground link - if A is checked (along with any others), description field shows.

[Zhenglish]

Hum, the 'contains' in the oneOf stops working when I have multiple controls. In this example, I have 2 checkboxes, and each controls a text field. They work by themselves, but stop working when both selected.

Any suggestions?

[dylanfprice]

Yeah I just encountered that one too. You have to enumerate the cases which is a bit unsavory but it works. Playground link.

Beyond about 3 controls it becomes a good interview question to generate all the cases :smile:

You'll want to follow https://github.com/rjsf-team/react-jsonschema-form/pull/2506 which should make it a lot easier.

[Zhenglish]

There is a warning message in console "react_devtools_backend.js:4045 ignoring oneOf in dependencies because there isn't exactly one subschema that is valid". This occurs when no item is select, so I added a subschema for that scenario. However, I couldn't make it right. Can you please look at my playground?

[dylanfprice]

contains matches items within an array so contains: {const: []} doesn't do what you want. You need something that will match an empty array, maxItems: 0 works. playground

@epicfaace I think you can close this

thanks!

是的，我也刚遇到那个。你必须举一些命令人反对但有有效的例子。游乐场链接。

除了大约3个控制之外，它成为生成所有案例的一个很好的面试题😄

你会想要跟随#2506这应该会让它更容易。

The more options you have, the more code you write. Is there a better way to do this?
