Radio is one of the generic HTML Form input elements. In the Form Builder, one is able to define the options available to the Select Box via various means, including the use of Options Binder.
The easiest way to see how the Radio button works are to use the existing built-in App Expenses Claims. Here are the steps:

- Log in as admin and click on the pencil icon on the Expenses Claim to open the Design App. (see Figure 1)
- Click on the Create New Form button and fill up the Form Details as follows (see Figure 2):
- Form ID: radio
- Form Name: Radio
- Table Name: j_expense_claim
- Drag and drop a Radio element on to the canvas.
- Hover the mouse over the Radio element on the canvas and click on Edit to open up the Edit Radio properties.
Fill up the following fields as follows and click on OK (see Figure 3):
