How to create custom space block below catalog.topnav ( Menu )

Question

I want to add add-to-cart and Wishlist under catalog.topnav ( Menu ) how to add right below menu bar.

Answer 1

You just need to move minicart to catalog.topnav use :

<move element="minicart" destination="catalog.topnav"/>

at

app/design/frontend/{Packgae}/{theme}/Magento_Theme/layout/default.xml

Update I:

If you want minicart below nav you need to create a custom container and need to move it, like:

    <referenceContainer name="page.top">
        <container name="test" htmlTag="div" htmlClass="test-class" after="navigation.sections"/>
    </referenceContainer>
    <move element="minicart" destination="test"/>
