The error isn’t helpful so we should have a more helpful one saying to use select_input with an attribute

I think it's just a matter of adding a type signature to the options parameter

lucky/src/lucky/tags/base_tags.cr

Lines 167 to 169 in 8d7bb57

	def {{method_name.id}}(options = EMPTY_HTML_ATTRS, **other_options) : Nil
	{{ method_name.id }}("", options, **other_options)
	end

The default arg is Hash(String, String) but I'm not entirely sure if that is always how people use it
