Checkbox indeterminate state #502

Closed dsshep closed 2 years ago

dsshep commented 2 years ago

What is the correct way of setting a checkbox to an indeterminate state? There seems to be no logical way within the API. If there isn't, perhaps prop.isChecked should accept a Nullable<bool> or bool option to support this?

No problem, figured it out. You need to use the ref callback, which may pass null, and you'll need to have open Fable.Core.JsInterop to use the ? dynamic syntax:

Html.input [
    prop.type' "checkbox"
    prop.ref (fun e ->
        if e = null then () else
        e?indeterminate <- (* set the bool state here... *))
]
