Howdy, @jameswilson!
Thanks for writing in! As mentioned previously, UberMenu has its own set of self-contained styling and options, so for anything related to that you would want to visit their official documentation:
There might be some information in there that explains how to style the search on a mobile layout. As for the padding being too much on mobile, could you expand on this a bit? Are you referring to all the empty “white space” to the right of the menu items? Again, this would be an UberMenu styling thing, and this is also a common convention for mobile menus to have their items go fullwidth so you can see them stacked vertically on smaller screens.
If there is something else specifically you need help with related to X and its own options, we’ll be happy to help you out with that and for any UberMenu questions, their documentation is the best source of information to achieve a look you’re after.
Cheers!
