A Radio button control can be used when the user is supposed to select any one out of the given choices. Radio buttons are shown in radio groups to show a set of related options. For example a Radio button can be used for accepting the gender of the user. The user can check either the male or the female option.
- Label: Label is the text that is displayed above the text box and helps the user to understand what the Radio Button is for.
- Properties: These properties help you customize the Label by changing the text size, weight ( Light, Normal, Bold, Extra Bold, X Extra Bold), alignment (Left, Center, Right, Justified) and color of the label.
- Type: The Type field is automatically generated depending upon the type of control used. In this case, it is a “radio” type.
- Unique Name: A Unique Name is used to uniquely identify a control in your App. Every control that is added on the screen gets an auto-generated Unique Name on the basis of the Label name given to the control.
- Submit Data: This field lets you determine whether to send the value of the control or not in Workflow based on various control states. There are three conditions that could be set for this field.
- Always: When this condition is selected, the checked radio field will be submitted irrespective of the state of the Radio Button.
- Never: When this condition is selected, the checked radio field will never be submitted irrespective of the state of the Radio Button.
- No When Hidden: When this condition is selected, the checked radio field will be submitted if the Radio Button is visible and not submitted when the Radio Button is hidden.
- Required: When you select the required option, the field becomes a mandatory field and the user can not submit without filling it.
- Read Only: When you select this option, the user will no longer be able to edit this field.
- Hidden: The hidden option helps you to hide the field from the user. This might help if you want to show certain fields only when a specific condition is met/not met.
- Caching: When the caching option is selected and if a LOOKUP formula is applied to this control, the state that the LOOKUP returns will be cached and the user will be able to see this state in the Radio Button even when the user accesses the microapp later with no connectivity. This option is required when you want your app to be accessible in offline mode as well and getting the latest data from the sheets always is not critical.
- Hide Label: This option hides the label of the Radio Button from the view.
- Others Option: This option allows respondents to provide an answer that is outside of your predetermined list of answer options with the help of a text box.
- Placeholder: This is an option that becomes visible when you select the Others Option. It is a prompt that gives a hint to the user as to what has to be done and is overridden when the user types something into it.
- Theme: The theme lets you choose the color of the Radio Button. You can either enter a custom hex code value or use one from the available themes in the builder.
