The captcha component is a Google widget whose purpose is to allow data submission only when filled out by a human.
Component properties
The component can be placed on the form multiple times, and its display can be conditioned on a satisfied condition.
Illustration 1. Captcha component displayed on the form
Entering the value of the captcha placed on the form is always mandatory - verification will be positive when the "I'm not a robot" checkbox is marked and optionally other actions are performed (enforced by Google).
Illustration 2.In the example, the "I'm not a robot" checkbox was not selected, which caused the validation error message to be displayed
The component validation occurs after the image is correctly selected. The component stores 3 types of states: too long a waiting time after verification - "expired", positive verification - "ok" or negative - "noOk". Interactions on the form can depend on the component's state.
