Can I set the drawer always show?

[Mr-ShiHuaYu]

Hi, first of all, thank you very much for open-source this project, I like it very much, it is very easy to use and supports a high degree of customization.

It may be my first day to use this project. Now I want the left menu bar to be displayed all the time, and do not block the right window when it is displayed. After I read the documentation and tried it by myself, I still couldn't find the idea. Excuse me, can you give me anything help?Thank you very much.
