Learn how to add a custom radio field to any USP Form.

Step 1: Use the following code for your Custom Field definition:

field#input_radio|radio_inputs#Option 1:Option 2:Option 3|radio_checked#Option 1|desc#My Label

Step 2: Add the custom-field shortcode to your form, for example:

[usp_custom_field form="123" id="1"]

That’s all there is to it. Here is a screenshot of the radio field we just built:

USP Pro - Radio Field

Note: To see a live example of a custom radio field, check out the “Starter” form demo, included in USP Pro version 2.3 and better (visit USP Forms > “Starter Form Demo”).


Here are the attributes available for custom radio fields:

  • field – specifies the type of custom field
  • radio_inputs – list of radio inputs
  • radio_checked – specifies which radio input should be selected by default
  • data-required – make the radio field required
  • desc – adds a description/label to the group of radio inputs
