i want to hide my logo bar

Hi there,

in Appearance > GeneratePress - you can activate the Menu Plus module.
Then in Customizer > Layout > Off Canvas you can enable the off canvas for mobile and select the Overlay option.

I did not get any menu after done all settings. All the options that used to appear in the menu are now disappeared.

Hi there,

Just to be clear, you want to hide the logo when menu is opened on mobile?

If so, can you reverse back to the previous setting, then add this CSS:

html.mobile-menu-open .site-logo {
    display: none;
}

I didn't mean that I just want to show the menu on mobile which now has an X mark in the middle. And now no category is showing in the menu.
how can I make menu in mobile like - neilpatel.com

Create your menu in Appearance > Menus, and in the menu locations, select Primary Navigation and Off Canvas Panel.
Once that is done go to Customizer > Colors and set the colors for the Off Canvas Panel.
