You can now configure Sections to have no formatting associated (borders, spacing, or indentation). By default, if you have Sections and especially embedded Sections it will apply certain spacing and indentation to the form to delineate each Section.  But sometimes a user wants to use a section for configuration scale or complexity, and not for layout purposes and doesn't want to impact the way the form looks.  Now within the Sections gadget you will have the Hide Section borders and spacing configuration option:

Some common use cases for this functionality:

• Apply conditional permissions to a large number of fields, but you don't want to impact the way the form looks by embedding a visual section.
• Setup a small set of forms within a section to be Office Use Only, but you don't want to impact the visual display of the form.
• Setup complex Conditional Visbility Rules that include and as well as or logic, but you don't want to leave visual artifacts by embedding multiple visual sections within.
• Have a section header to create trackable headers for accessibility, but you don't want to sacrifice horizontal real estate on the screen, especially in a product where we have multiple sidebars.

Note:  If a section is at the top level of a repeater or document there will still be some spacing that remains, however any sections embedded within other sections will be fully invisible.
