How to Hide and Show "Section Type"

Please refer to the attached image. Is it possible to display only the section name "Internet Services" and hide the section name "Request Details"? Additionally, when the user selects a value from the "Network Services" dropdown list within the "Internet Services" section, the second section should be displayed. This second section should contain the fields relevant to the selected value, based on the existing field and form rules?
