Question, how to reduce Maximenu CK's width size.

Dear support team,

I made a left sidebar using the Maximenu CK, like shown at jrmax55.cafe24.com/p-1/origin.html .
I looked for how to reduce the size of the width of the left sidebar as it seems to be wide a little, but I have not still been finding it.
Could you let me know how to do it?

Best Regards,
Adrien Park.

Hi
I don't understand the relation with maximenu, if you want to reduce the sidebar you must do it in your template.
