How do I clear a radio button?

Is it possible to deselect a choice in a radio button group on a fillable PDF? There are times a radio button choice may be selected accidentally. When this happens, the only choice one may have is to abandon the form they have been completing, and start from scratch in hopes the mistake is not made again. Our forms are very detailed and with multiple pages and combinations of drop downs, check boxes, radio buttons, text boxes, etc... with questions totaling well over 100. You can imagine someone's frustration if they've completed over 100 questions and near the end of the form there's a radio button question they did not mean to answer... The radio buttons are used exclusively for one choice selections only, otherwise check boxes are used. I'm interested in any simple solutions. Maybe Adobe can come up with a solution. I don't understand why radio buttons don't function the same way as check boxes. If you click once, it's marked; if you click again, it clear. Any help is greatly appreciated. Detailed steps for the fix are also appreciated. Thanks!

This is the functional definition of radio-buttons. Once a selection is made, you can only switch from one button to another, not de-select them entirely (unless you reset the form).

If you want to be able to de-select the buttons then you should use check-boxes. Give them the same name but different export values and they'll function just like radio-buttons (ie, when you click on button in a group the selected one becomes un-selected), with the additional feature that you could de-select a button but clicking it.

Yess I found a quick solution to this radio button problem using Chrome.
If you can't deselect it a radio button, go to Google Chrome > File > Open File and then open your PDF in Chrome, the radio buttons will be instantly changed to squre select checks, and you can unselect them. Make your changes and then save the PDF with your changes in it. Solved!

To all the Prepare Form>Clear Form suggestions...

This is NOT something the end user is going to do as it requires Acrobat Pro or Standard.

Also, the OP stated they DON'T want to clear the form and start over again.

The easist way, without code, is to use check boxes but name them like you would a radio button.

Attached is a sample of radio and checkbox options--look at the last one on the page. That sample operates just like a radio button but allows the end user to deselect.

(As a side note, when I use radio buttons, I include a 'No Answer' option. That way, you know the end user is purposely not answering the question and did not accidently skip over it.)

hello,

I was following the advice to switch from radio buttons to check boxes which worked well for most of my form... but some of my (now) check box export values are the same $$$ so if I check one, the check appears in 4 of them. is there a way to use check boxes with the same export value so acrobat will treats them all as individual?

No. You must give each one a unique value. It can even by "1" and "1.0", "1.00", etc., though.

Form is on the screen

Click on the menu, choose All tools - prepare form

On the form select (click and drag) the radio buttons you want to clear

Click on the 3 dots in the field pane (top right hand side)

Choose clear form

Only if used immediately. If you save the file, close it, and then re-open it, for example, it doesn't work.

I think the simplest way to correct this and reset all radio buttons back to empty is to prepare form -> click one of the radio buttons that already exists in the group, copy it, paste it, and then exit prepare form. Check that radio button and it will be selected. Then prepare form-> delete that one radio button. All are now empty!

That's probably the most difficult way of doing it...

I realize this is an older issue, but there didn't seem to be a clear answer anywhere else. So instead of having to clear the entire form, you can go to Tools>Prepare Form (open the tool). Then select the button that is checked and delete it. Then copy/paste another identical radio button from the form into the right position and then rename.

There should be a way to change the field value of the button to change it back to being unchecked, but I was unable to make it work in the 15 min it took me to figure out I could just copy/paste an identical empty radio button into it's place after deleting it.

Editing the form to clear a radio button group is very inefficient--also, not everyone has the ability to edit the form.

You can easily make a button to clear JUST the radio group OR you can use pseudo radio buttons. See my post from Sep. 05, 2023.

All the answers here are frustrating. If you are on the user end and accidentally selected a "yes" or "no" where you want to leave the question unanswered there is absolutely nothing you can do. Clearing the form is fine if that's the ONLY change you made since opening it, but generally one does not want to have to go back and re-key the entire form just to fix one response. Even if you can crack open the form, editing those radio buttons isn't as straight forward as one might like. Massive time suck created by something that is supposed to make filling out a form easier than printing, completing by hand, and scanning.

You can create a clear button that resets ONLY the radio buttons OR you can use check boxes but set them up like a radio button. The latter option lets the user select only one choice but can deselect if desired.

Typical Radio buttons: Same Field Name; Different Option Export Values.

Typical Check boxes: Different Field Name; Same Option Export Value (e.g. Yes).

"Pseudo" Radio Buttons: Use Check boxes with Same Field Name; Different Option Export Values.

If you want to modify the behavior of the radio button group such that the selected radio button can be unselected by clicking on it then here is one way to do it. For this example consider three radio buttons in the group and the radio button group's name is "RadioButton1". The following code should be added as a document-level script:

var rb = getField("RadioButton1");
rb.exportValues = [ "First", "Second", "Third" ];
var cval = "";

The following code should be added to every radio button that should be unselected:

if (cval==rb.value) {
  rb.value = "";
  cval = "";
} else {
  cval = rb.value;
}

I have included an example PDF document with radio buttons that behave as you required.

Use check-boxes instead of radio-buttons.

One way to do this is to toggle the option "button is checked by default" on/off.

If you, as the form creator/owner, want to reset the form, you can just do it the way it's mentioned below (Tools - Forms - Preapare Form - More Options - Clear Form). BUT, if you want the end user to be able to deselect radio buttons or you just want a quick way to clear the form (or just specific fields) it is possible to add a button to your PDF to do just that.

Here's how to create & label the button:

Place the button form field on your form where you want it, give it a name and click the All Properties link. This opens the Button Properties dialog box. Click the Actions tab, then choose Reset a form in the Select Action from the drop down list. Next, click Add..., and select the fields you want to reset in the Reset a Form dialog box. Click OK. On the Options tab you can give the button a label. If you don't, the button will be blank and the end user won't know what it's for.

In Acrobat 2024, if you are the author creating the form and need to reset it after testing, go to All Tools > Prepare a Form. Then in the Fields panel on the right side there is an Options menu (three dots) which has Clear Form.
