I'm new to web applications in general, and I'm starting with Rails. I'm trying to create a 'dropdown' menu in the html.erb file using the 'form.collection_select' command, but I'd like it to include Paginate and Search Item. The biggest issue is pagination; I spent several days searching in the internet but was unable to find any solution. I could add pagination like this

, but it isn't what should be. How do I make a dropdown menu using paginate that is inside the dropdown-menu? javascript? css?
