reflect_os_kernel

defmodule ReflectOS.Kernel.OptionGroup do
  @moduledoc """
  Creates a visual grouping of configuration option inputs in the Console UI.

  ## Struct Fields

  * **label** [required]: Title of the input grouping.
  * **description** [optional]: A single arity function which can be passed to `Phoenix.LiveView`.
  * **options** [optional]: List of `ReflectOS.Kernel.Option` which should be
  displayed in the input grouping.

  Note that `description` takes a single arity function which MUST take an argument called
  `assigns` and return the result of a `Phoenix.Component.sigil_H/2`.  This allows
  you to use html markup in the description.  The ReflectOS Console uses the
  [Flowbite CSS Library](https://flowbite.com/docs/getting-started/introduction/)
  for styling, so feel free to use any of the css classes that it provides!

  ## Example

      %OptionGroup{
        label: "Label",
        description: fn assigns ->
          ~H\"\"\"
          The label appears over the section, and can be optionally shown or hidden.
