Binding a datalist to an input relies on a direct reference between the two elements. The input carries a list attribute, and that attribute’s value must be the id of the datalist. This exact matching tells the browser which list of options to show as you type. The datalist’s id provides the unique identifier for that list, and the input’s list value points to it. When they match, the input will present the predefined options from that datalist as suggestions.

For example, the input might look like: <input type="text" list="cityList"> and the datalist would be: <datalist id="cityList"> ... </datalist>. The name, value, or type attributes are unrelated to binding the datalist, and the for attribute is used with labels, not for linking datalists.
