Default value

This is the default value that you want to add so that the end user will see the pre-filled data and doesn’t need to input any data in the single line text block.

‍

Required

Enable this option if you want the user to compulsorily input the data. If enabled, the end user can submit if and only if the data is entered in this field.

Advanced Options

Enable this option to show the advanced options to configure the single line text block.

Display this field if

Use this if you want to show or hide a field under certain conditions. It accepts the standard Clappia Formulae, similar to conditional sections.

1. You can type ‘@’ to get a list of all the variables in the app and select variables.
2. Using these variables you can write Excel-like formulae.

‍

Example: For a Yes or No question, you can show the remarks field when the answer is No.

Allow value to be changed after initial submission

This option is enabled by default. End users can edit the value entered in this field after creating a submission. Disable it if you do not want the end users to edit the submitted value.

Example: A new submission has been created in the Customer Visit app. You do not want the customer's name and other details to be edited by anyone after the submission has been created.

‍

You can also write a formula here to conditionally allow editing of the data in the block after submission.

‍Example: In the customer visit app, the customer email field should be editable if and only if the status of the submission is not equal to Confirmed or if the user is an admin.
