Hi Qing,
If you look carefully at your second image, you'll notice that the row actually isn't empty, because it still contains the submit button for the filters. So your CSS will need to account for that as well.
You might try something like this instead:
#lia-body .lia-content .lia-component-search-content form.lia-search-message-mobile {display: none;}
A couple of caveats:
- You'll want to fully test this out to ensure that it's hiding everything you want to hide, while not hiding anything you don't want to hide.
- You and your team have probably already carefully weighed this decision, but I do want to call out that removing these options may make it more difficult for your mobile users to find the content they're looking for.
I hope this helps!
