<datalist> size and style
I'm creating a contact form and I was using the <select> tag and I discovered the <datalist> tag and I think it's very useful, because it's dynamic (you can write and have some options at the same time). The problem is that I can't minimize the list of option with size="5" like with <select> tag. With <datalist>, I have like 30 options showing at the same time without scrollbar, so we can't see all of them...
My suggestion is to add css style like with <select> to change how the datalist look (color, shape, etc) and to be able to only show the first X amount of options in the list when you are clicking to write what you want.
