Hi,

Does anyone know if there is a way to make all options in a SELECT
element become unsuccessful so it behaves like a group of radio buttons
in which no button is checked?

Am I the only one that is thoroughly confused by this question?

Please restate your question in a different form, I have no idea what
you are trying to achieve.

Probably not.

It's always a good idea to explain what you are trying to achieve, rather
than an assumed technical solution to an unspecified problem, especially
when the assumed solution is a dead end.

However, my crystal ball whispered to me that August was trying to ask "Is
it possible to have a SELECT element where no option has been pre-selected".
The answer is "No, not in any reliable manner, but if you just don't use the
SELECTED attribute, then most browsers behave that way." The good question
then is: Why would you rely on that?

If the value of a button is either "on" or "off", then all that is
necessary is to make the value of all buttons "off".
Or could it not be possible to have one button "hidden"?

What do buttons have to do with select and option elements?

If I'm understanding you correctly, you want to create a <select>
element where all the <option>s are unselected. As far as I know,
there's no way to do this; there must always be one option selected in
the list. I think what people normally do is have one blank (or
"fake") option, which can be treated as the default. Then none of the
"actual" options will be selected.

Apparently my question was not so clearly stated.

The term "successful control" is used by W3C to mean a control for which
a name/value pair is submitted. With this terminology an unchecked radio
button will become unsuccessful when the form it belongs to is submitted.

Ideally I think you should be able to change a choice made through radio
buttons to a drop-down list (or vise versa) without changing the program
which processes the submitted form (a kind of view-controller
independence). However, since at least one option in a SELECT element
will always be selected it will also be submitted.

Unless I am wrong I think I have answered my own question, i.e. it is
not possible.

You can make any form controls "unsuccessful" by don't giving it a
"name". If name attribute is not available that control will not get
submitted. For your scripting needs you can use the id attribute.

Form controls can also be made unsuccessful by disabling them.

An option in a SELECT element do not have a name in the first place and
radio buttons are grouped by name so that will not work.

That might be an option though (or maybe more of a "hack" in this case).

By the way, I have learned that, as with SELECT options, at least one
radio buttons must always be checked.
