VSCode having multiple types in the configuration

Question

How would I have a type that requires a boolean or null? The relevant snippet that I was able to one up with:

"something": {
    "type": ["boolean", null],
    "default": true,
}

When I used this and tried to change that in vsc, there was only an option to copy that option into the User Settings/Workspace. But, with a boolean type by itself, it'd show true or false when changing the value. How can I implement this so that when attempting to edit it in the settings, it'd show true, false or null in the edit popup?

EDIT: I was able to get the pop up when using "enum": [true, false, null]. Still curious if there are any other ways.

Use the string "null" instead of null itself:

"something": {
    "type": ["boolean", "null"],
    "default": true,
}
