How to add search bar in my store page in the same section with my product list ?

Hello guys ! My name is plum I try to create ecommerce about meat website. I'm new here in this forum.

I have problem with adding search bar in my store page. I want my product search bar above my product catalogue but under the title name. Squarespace feature does not allow me to customize it in the same product list section... they only need me to create a new blank section and add new box and click search then it really separate apart from my product list ! Which I do not want it like that ...

Also I don't want to create a search page separately it's not good for user friendly ...

Hope you can help me out and recommend the solution to this problem.
