Introduction

The Hidden Field is a standard HTML input element. Unlike Text Field, Hidden Field does not show up on the page, hidden away from the user. It is typically used to pass/set temporary or session-based information.

Get Started

The easiest way to see how the Hidden Field works are to use the existing built-in App Expenses Claims. Here are the steps:

  1. Start the Joget Server and open the App Center.

  2. Log in as admin and click on the pencil icon on the Expenses Claim to open the App Composer. (see Figure 1)


    Figure 1

  3. Under Form Builder column, click on Expense Claim New (see Figure 2)


    Figure 2

  4. Click on the Hidden Field element entitled status to open up the Configure Hidden Field properties. (see Figure 3)

  5. Click on Preview to open up the Preview tab, and you will not be able to see the Hidden Field.
