Search Bar in Menu

I would like to add a search bar to my main menu. Is there a good module that works well with this template?

Hi,

Is there a good module that works well with this template?

There is almost 10 different search modules on JED, so I really don't know.
But I'm sure that most of them can work without any issues.
Good for me it's doesn't always good for you, besides we can not support all additional extensions.

But GK templates allows you to add module inside menu as a menu item (under), check documentation page for more details.

I have added search as a menu item but I would much prefer a search bar instead of having to click to a whole new page and then search

I fully understand. But it request template php/css code customization which is not a part of support.
So for "free" I can only suggest you few tips:

1) Create a new module position next to menu (guide is in our documentation section)
2) Use CSS to fix positions, because menu and search must be on this same row.
