There is no native radio button feature in Adobe InDesign, but there are a few ways to create the appearance of radio buttons. One way is to create a group of circle or square icons, and use the 'Guides' tool to draw lines connecting the top and bottom of each icon. This will create the appearance of radio buttons that are 'linked' together.
Another way to create the appearance of radio buttons is to use checkboxes. To do this, create a checkbox field and give it a unique name. Then, create a script that will 'check' the checkbox if the field is clicked. This can be done by going to 'Window > Utilities > Scripts', and then selecting 'Adobe JavaScripts'. In the 'Adobe JavaScripts' window, create a new script and paste the following code into it:
if (event.target.isField) {
event.target.checked = true;
}
This code will check the checkbox when the field is clicked. You can then add additional checkboxes and give them the same name, and the script will check the first checkbox in the group when any of the other checkboxes are clicked.
