Position Jump on Page Load

Hi there, I love this plugin it has saved me hours of coding!

However, my client is now requesting that the page loads smoother without the page jump. Currently the page loads with the menu fully expanded and then contracts (in a fraction of a second), this gives a jumping effect. Is there a way to load the menu contracted and expand if needed?

Example of this available at: holdenharper.co.uk

I have read lots of unresolved “jumping” posts on stackoverflow and css-tricks in regards to jQuery accordion, is there a resolution for this?

Many thanks!
