Web forms are essential in user-website interaction. Whether it's performing a search, signing up for a newsletter, or completing a purchase, forms are ubiquitous. Fortunately, HTML5 introduced several improvements to make life easier for both developers and users, being <datalist> one of the most useful and least known tags. This tag allows you to provide a list of suggested options to users as they type in an input field, significantly improving the usability of web forms.
What is datalist in HTML?
The element <datalist> HTML works in conjunction with other input elements (), allowing to define a set of predefined options that the user can select. As the user begins typing in the input field, options that match the entered text are displayed as a drop-down list, making selection easier and reducing the chances of error.
datalist use cases
Predictable Searches
A classic use case of <datalist> It is in search fields where common or popular terms exist.

Standard Form Fields
Another common scenario is in forms that include fields such as countries, languages or time zones. Thanks to <datalist>, users do not need to remember the exact spelling of each option, simplifying the form completion process, a detail that is reflected in a lower form abandonment rate and greater user satisfaction. A contact form in https://nelkodev.com/contacto, for example, could benefit from this functionality by requesting the user's country.
Dynamic Forms
In situations where forms change content dynamically, <datalist> becomes an essential ally. Imagine an inventory form where product names need to be entered manually. With <datalist>, you can offer a list of products that already exist in the database, thus avoiding duplicates or spelling errors.
Specific Data Entry Fields
When users must enter specific data, such as product codes, equipment models, or part numbers, <datalist> helps limit the range of possibilities, reducing input errors and ensuring the consistency of the data collected.
