Presentation section — UI adapter, template, features, and theming.

Controls how the form renders: which ui_adapter supplies the per-component renderers (button, text_input, etc.), which template arranges them, what subset of features to enable, and the default theme classes used by every field/group/error slot.

Example

presentation do
  ui_adapter MyApp.UIAdapter
  template MishkaGervaz.Form.Templates.Standard
  features :all
  debounce 300

  theme do
    form_class "max-w-4xl"
    field_class "rounded-md"
    label_class "text-sm font-medium"
    error_class "text-red-600"
  end
end

Notable options

• ui_adapter — module implementing MishkaGervaz.Behaviours.UIAdapter. Defaults to MishkaGervaz.UIAdapters.Tailwind.
• template — module implementing the form template behaviour. Defaults to MishkaGervaz.Form.Templates.Standard.
• features — :all (use everything the template supports) or an explicit list: [:validation, :uploads, :groups, :wizard, :autosave, :inline_errors].
• debounce — global default phx-debounce in ms; overridable per field via field :foo do ui do debounce 500 end end.
• theme do … — string-class slots (form_class, field_class, label_class, error_class); template-specific options go in extra: %{…}.
