note

When a parent of a child collapsible item is collapsed, its child items effectively stopped being rendered by React. This means the collapsible status of any child collapsible groups will return to the default values ("default-open" or "default-closed") as defined in the Questionnaire.

EntryFormat​

Displays a "ghost" text in the field. Acts as a guide for the user on what to enter in the field.

It disappears from the field after text is entered.

EntryFormat is only supported on decimal, integer, string and text "text-field"-based items.

Basic Usage​

Questionnaire-unit​
