Thank you very much for you reaction. I also thought that it would be done automatically with setting-up the menu correctly. But in my situation it still doesn't work.
I checked some code I think that I am found the reasion why I don't have the bulluted list appearance in my mega menu. I use replete not as e-commerce website and don't have WooCommerce installed. After I installed Woocommerce the bullets appear.
But is it nessecary to have Woocommerce installed for a correct working of the Replete theme? Or is there a mod to tackle this issue.
When it's nessecary to have Woocommerce installed how can I hide the cart option in the header?
I look forward to hear from you.
