This request is from "Hitachi Energy USA Inc.
As a suggestion, Customer wanted to hide all the sub sections and show only the Main section when we try to collapse. For example when we click on section and collapse it, all the QA pair will be under the section and it will not be visible. Customer wanted the same feature for the sub sections. When they click on Main section name and collapse, all the sub section should not be visible and only the main section should be shown.
As mentioned in the screenshot customer wanted all their sub sections to be hidden under the Main section.
