Search module on top split menu

Hi,

I know how to get search module on top of megamenu but can´t figure out how to make it appear on top of the split menu, any help? I mean that the search molude should overflow on top of the right corner of the split menu. Thank you!

Hi,

Can you use a picture with annotations to help me understand it clearly? Also an URL would be helpful for me to check and give you solution.

Thanks,
