[ihouvet]

Overview

A feedback module in being built which would allow end-users to add comments to Shesha pages views. It should be possible from the selected DOM element to determine which is the closest form component, sub-form (if applicable) and rendered form.

See: https://chatgpt.com/share/e/6762e996-5c14-8010-bf1b-58b2d5f4d916 regarding adding custom attributes to HTML elements.

Acceptance Criteria

1. For form configs: Add a class sha-f to the root element of a configured form to help us easily identify configured forms and add custom data attributes e.g. data-sha-form-id (then feedback client tool will have to look up the additional required information); data-sha-form-is-top indicating if top level form
2. Similarly for the form components: add sha-c class and data-sha-c-name, data-sha-c-type attributes
