You cannot directly bold only one radio button value using the basic configuration, so you need a small CSS tweak. First, give your radio button control a custom style class, for example myRadioOptions, in the Presentation tab of the cell. Then, in your skin or custom CSS file, add a rule that targets only the specific option you want to bold. For example, something like: .myRadioOptions input[value="Option1"] + label { font-weight: bold; }. Here, "Option1" should match the actual value of the radio option you want to highlight. This CSS will make only that label bold and keep the other radio options normal. After saving and deploying the CSS, refresh the UI and you should see that only the chosen radio value appears in bold. This approach works for both of your examples where the “default” option needs to stand out visually.
