MenuContent

@Composable
private fun MenuContent(options: List<DropdownOption<T>>, isRequired: Boolean, isLoadingFirstPage: Boolean, isLoadingMore: Boolean, errorMessage: String?, onOptionSelected: (DropdownOption<T>?) -> Unit)

Renders the main content of the menu.

Loading the first page replaces the list, loading another one adds an indicator below it - otherwise the list would disappear every time a batch is added.
