Sub Menu Indent

I have a custom side bar menu with parent, child and grandchild levels. How to I indent the child relative to the parent and indent the grandchild relative to the child.

Thank you for your help

Hello there,

Please share your site link with us so we can inspect it in order to try to generate necessary css code.

All the Best!

If you go to this page http://www.euhcm.com/project-development-consulting/ you will see what I mean.
Project Development & Consulting is the Parent
Project Management and Feasibility Studies are the Children.
Action Plan Development and Gap Analysis are the Grandchildren

I use the following ugly hack to indent the Children relative to the parent but I also need to indent the Grandchildren relative to the Children.

.widget ul.sub-menu li a { padding-left: 40px;
}

Thank You

Hello again,

Custom side bar is not present or referred page, have you managed to fix it in the meantime or you have given up?

Best Regards!
