Here's a sample playground link.

Bug: When using allOf, with one of the options is an array with uniqueItems: true, a minItems set to greater than 0, with the checkbox widget, and with omitExtraData and liveOmit set to true, then the user cannot check any checkboxes.

Playground reproduction here (check the boxes "Omit extra data" and "Live omit")

This bug was fixed in 4eccffa.

Why is this a git dependency?

[epicfaace]

It links to my PR here (mokkabonna/json-schema-merge-allof#5), which makes sure that mergeAllOf can be called with deep: false and thus only merges a top-level allOf. It's not strictly required, but I guess it's a performance improvement.

[epicfaace]

Since it's not strictly required, I'll just remove it since that's better than depending on a git dependency.

Aside from tests and docs, is this feature complete as-is? If not, how can I help out?

[epicfaace]

@erunion tests, docs, and a playground example. Feel free to help out with either -- just let me know on this PR!

[erunion]

@epicfaace I can help out with a playground example.

Hello all,

I would be really interested in having this merged. Is there anything I can do to help knowing little to nothing about React?

[epicfaace]

Remaining todos:

• update docs
• figure out whether we're going to depend on a fork of json-schema-merge-allof (Add "deep" option mokkabonna/json-schema-merge-allof#5) or implement this logic within rjsf ourselves

Hello All, this is holding up an important fix very far downstream elsewhere - is there any hope of seeing this PR resolved any time soon? Is there anything a novice can do to help? Thanks!

[edi9999]

Looks good to me, we can merge if you think it is good

[PaulNendick]

Thanks everyone!
