Mega Navigation menue with links open same page (e.g. framed)

Hello, i want something that works like the bookmarks bar, but as a Mega Menu. As such extension doesnt exist fro Chrome, i want to use a Mega Menu, and the Links shall open in the same page below. The links are all external pages (e.g. google docs, etc.), but shall open in same page below the bar, so the bar is always available. Sample: [login to view URL] (Menue itself is on [login to view URL] Problem: but as the frame do not autoadjust it doesnt work properly as you can see. Maybe there are other solutions that to make it framed. i dont know. Tasks: 1. Make a solution (either autoadjust frame, so the menue always works) or any other solution that enables to use the mega Menue bar as always present bookmarks menue. 2. Instead of editing [login to view URL] (the menue html) i want a separate file with link values (Value Link 1="...link; ...), where i can edit the links more comfortable, and placeholders in the [login to view URL] where this calues are included (by php or however)
