Move search box under navigation bar

Hi, I would like to move the search box a bit down : from the top to under the navigation bar. I see many solutions in this forum but all are for earlier versions of Opencart. Where can I change the code to move the search box for the most recent version of Opencart 3.0.2.0. ? Thanks !

Hi
If you are using default theme, it is here:
catalog\view\theme\default\template\common\header.twig
<div class="col-sm-5">{{ search }}</div>

You can play around with CSS to do this. Make sure you are not going to modify core files for future upgrade reference.

I can find the file :
catalog\view\theme\default\template\common\header.twig
<div class="col-sm-5">{{ search }}</div>
but what can I change to bring the search box under the category bar ?

You can shift this column to up and down wherever it is required to placed.
You can create OCMod xml file to do this.
