When working with a form that uses multiple tabs, you can specify which tab to be displayed by default upon opening the form.

## Tutorial

To use this feature:

1. In the **Field Key** tab of your **Tabs Component**, go to the **Custom Properties** field.
2. Click **Add Another**.
3. In the **Key** field enter `defaultTab` .
4. In the **Value** field enter the index number of the tab you want to display by default. The **Value** field support only static values.
   :::important
   The index count for tabs starts at 0. Therefore, a 5th tab has the index number `4`, a 3rd tab has the index number `2`, and so on.
