Hi Mary,
It is because I have to turn off mobile view mode for my website to reduce the development cost. When I try to modify Eguru theme to be my own version, there are many features that I need to re-config or re-construct. And mobile view mode is not a customer's requirement, it is the best to turn of mobile view to reduce the effort of developing my website. Besides, I will try another option.
Thanks for your help Mary,
