Bootstrap based framework for page layout building

Question

I want to have page, where user can dynamicly add\del\change rows and panels.

I saw something similar in Graphana:

User can add rows and panels inside row dynamicly, also can change wide of panels (in "spans").

Does any similar frameworks already exist?

Use Laravel framework with some twist, you can get into what you want and also use bootstrap as you want for styling.
