I just wondered and wanted to gather together in one place all missing features of our beloved html form elements.
One example could be missing of horizontal scrollbar in a listbox. But I am sure there are a lot of features we would like to see in our form elements by default.
One missing feature per answer please.
Thank you.
Hell, they miss so many features, I wouldn't know where to begin! But here goes:
(Missing in HTML 4, don't know about 5)
Full visual customizability (background colours, borders, and text colours) for all elements (including checkboxes, radio buttons, and select
elements)
Native input validation (without needing JS) for text inputs: Numeric only, alphabetic characters only, regular expression
