Radio Button

A radio button is a graphical user interface element that allows a user to select one option out of a set of predefined options. Unlike check boxes, which allow multiple selections, radio buttons require that only one option is selected. To use the new version, refer to Radio Button.

Possible Uses

Radio buttons require only one selection out of multiple options. If there are only two options, a radio button is unlikely to be the best widget choice. One example could be selecting an answer on a questionnaire where the choices are: Agree, Neutral, and Disagree. Only one of these answers can be selected, because they are mutually exclusive.

Example

  1. Add a radio button and a header on a page.
  2. Specify the name in the Id box.
  3. Select the Global Data check box to set the selected value to global.
  4. In the Options box, select Hard Coded.
  5. Select + Add Option three times, and enter Agree, Neutral, and Disagree, and the corresponding values of 1, 2, 3.
  6. For the header, in the Data box, select the global value of RB that was set in step 3.
  7. Save the application, and preview it.

    The corresponding values appear in the header.
