Form fields only display single error

[TimMoser92]

Because of the following code, trestle admin only displays a single error even if mutliple errors exist for a single field. In my specific case there is a multi-select with two errors happening at once. The user will only be shown one at a time and has to fix them one after another.

trestle/lib/trestle/form/fields/form_group.rb

Lines 36 to 40 in 6cbe886

	def error_message
	content_tag(:p, class: "invalid-feedback") do
	safe_join([icon("fa fa-warning"), errors.first], " ")
	end
	end

I would suggest changing errors.first and iterate over all errors, sth. like this:

 def error_message 
   content_tag(:p, class: "invalid-feedback") do 
     errors.map do |error|
       safe_join([icon("fa fa-warning"), error], " ")
     end.safe_join("\n") 
   end 
 end

Nice suggestion, thank you. This was a shortcut I took early on, but it was easy enough to do this properly now.
