Each Dashboard has an "Overview" section, which is generally focused on Quantitative metrics and demographic data.
This section may include response data from a data collection program, but may also include already existing and/or operational data from your organization (CRM data, etc.)...
The options tab on the top right of the Overview Widget (three dots) will allow for you to:
(1) Re-order the information displayed in the Overview (via the left hand toggles)
(2) Select and de-select the response information that you would like to make visible/invisible in this section.
"Show more" and "Show less" Arrows allow for you to minimize any sections you would like to hide from view, as well as expand any sections you would like to see more of.
