Multiple values in custom vield

[joernheissler]

Hello,
I'd like to create a custom field where I can store multiple values. Is that possible? If not, is there already an issue (couldn'd find any)?

What kind of values? If it's an object value, then there is multi-object. If it's a selection field, then there is multi-select.

If you want a list of arbitrary string values, then:

• you could put them in a text field as foo,bar or foo|bar
• you could put them in a JSON field as ["foo","bar"]

A list of numbers could also go in a JSON field as [3,42]. And you could add a custom validator to check it.

Anything more sophisticated would probably store internally in JSON anyway. It would then be a question of how to make the UI work with multiple values (add/remove values, validate individual values etc) which sounds like it could be quite tricky.

It would be a list of DNS aliases, i.e. list[str] with a custom validator.
Inside the database it could be serialized as:

custom_field_data=

{
  "dns_aliases": [
    "host0",
    "host.with.dots",
    "host-two"
  ]
}

So I guess what I'm really asking for is a UI change: Instead of editing JSON directly, the UI would provide a simple list editor: One textbox per item, buttons to add/remove items, per-item validator.
