I made some modifications on the top navigation menu in Blank theme.
I need to change the position of the submenu.
I try to find some JavaScript
but no luck, then I see this in the Magento_Theme/templates/html/topmenu.phtml
<ul data-mage-init='{"menu":{"responsive":true, "expanded":true, "position":{"my":"right top","at":"right bottom"}}}'>
How I can change the position, I need to move submenu a little bit at top maybe 10px.
<nav class="navigation" data-action="navigation">
