HTML Form: Select-Option vs Datalist-Option

Think of it as the difference between a requirement and a suggestion. For the select element, the user is required to select one of the options you’ve given. For the datalist element, it is suggested that the user select one of the options you’ve given, but he can actually enter anything he wants in the input.

Edit 1: So which one you use depends upon your requirements. If the user must enter one of your choices, use the select element. If the use can enter whatever, use the datalist element.

Edit 2: Found this tidbit in the HTML Living Standard: “Each option element that is a descendant of the datalist element…represents a suggestion.”
