What type of constraint is required for radio button on a form to ensure a selection is made? Right now, the values match the text (Yes | No | N/A) but I’m not married to that, as I’m just starting the front end. I had tried a pattern just to match ‘Yes’, but the status stays valid at all times. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/a/8ac31d9edd6fd1ca9d05ff58f8e438c5e323f269.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/a/3a7abe9dd4428b926f01e16799ec4041d1c6a013.png) ---

In my 8.1.x radio group the options have a boolean called selected, I use that for validation. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/d/9d89d5fe65b479a536abdacad241022b93744e31.png) ---

Sorry, my friend, I’m asking is there’s anything for the built-in validation within the v8.3 form component. ---

The only available built-in constraint for radio button widgets is `required`. For anything further, you’ll need to utilize the `setCustomValidity` component function. > **[Perspective - Form Scripting | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.3/appendix/components/perspective-components/perspective-input-palette/perspective-form/perspective-form-scripting#setcustomvalidityinputkey-message-index)** > > This page details the various scripting, component, and extension functions available for Perspective's Form component. Scripting allows you to customize form behavior, handle validation dynamically, and respond to user actions. ---
