I have added the Ivory menu search sliding option on the nav menu bar. If you click the search icon, the sliding search bar background appears transparent. I have tried multiple times to change the background color to white or another color, but the transparent background is not being removed from the sliding search bar.
You can resolve the issue by adding the below CSS code in the Custom CSS option of Ivory Search plugin settings on the path Admin Area -> Ivory Search -> Settings -> Settings
.is-menu.full-width-menu form,
.is-menu.sliding form {
z-index: 99;
}
Additionally, if you visit this website from the mobile device, you will see that the search icon and sliding search bar are not responsive.
I have tested it and It is working fine for me.
