Add Menu Item to Front Matter

[VillageHubertChen]

• Add Menu Item to Front Matter as per description below. Talk to HC if any problems. We can change specs to keep implementation time under 1 hour.
• Fix double breadcrumb
• Set dyamic width to breadcrumb
• Set 2 field of title: 1) nav title 2) jumbotron

Problem

In above screenshot the menu entry: "V² Plan System Reference" is too long. If I were to shorten it to "Reference" only, it would work as Menu Entry. But the Title of the Article will then be shortened too to only read "Reference", which is not detailed enough for the Title. What I need are two fields in front matter. Please see below
