Hello. While working on my workbook I came across this sentence, in which I have to fill the adjective endings: Auf dem Markt gibt es allerlei... lustig... Spielzeug zu kaufen. My question is whether I should decline the word 'allerlei' in the usual way (allerleies lustuges Spielzeug) or like wenig and viel ( allerlei lustiges Spielzeug). I know that my question may be stupid but I'm really confused here. Thanks for the help in advance.
