Organize form fields that belong together into a tab. This makes filling the form straightforward and helps the user focus on one thing at a time. You can define a tab only inside a form definition . Tabs are displayed in the order which you define them.
Each form requires at least one tab. You cannot add fields without a tab.
Here is an example tab in the Contacts app. The first tab contains fields about the person and the second tab about their address.
Tabs look like this when rendered:
extends: Path to another tab that you extend. Valid values are absolute and relative paths in the
i18nBasename: Message bundle for localized labels. The bundle can be defined at dialog, form, tab or field level. Optional.
label: Field label displayed to editors. The value can be literal such as
Product nameor retrieved from the message bundle with a key such as
products.product.label. Use alphanumeric characters in literal values.
name: Name of the tab. Optional.
