Is your feature request related to a problem? Please describe.
Forms with many questions or with very different questions cannot be divided into sections for better clarity/visibility/readability. It's all one long list of questions.

Describe the solution you'd like
Add multiple descriptions in the form that do not contain a question and are not part of the results for the sole purpose of dividing questions into groups/sections and provide additional information.

Describe alternatives you've considered
Could be a question with a hidden field.

Additional context
Example: registration for a hackathon. There is one section for the submitter (name, email, phone), one section for the team (name, description, previous hackathons), and one section for the project description (name, excerpt, long description, category). Each section contains a short text with some hints on what to look out for while filling the form.
