To force category names to stay on one line in drop-down menus, you can use CSS to prevent text wrapping. Here’s a quick solution:
.dropdown-menu li a {
    white-space: nowrap;
}
This CSS rule applies the nowrap property to the anchor tags within the dropdown menu, ensuring that the text stays on a single line. If the text is too long, it will overflow horizontally, so you may also want to set a max width and enable text truncation:
.dropdown-menu li a {
    white-space: nowrap;
    max-width: 200px; /* Adjust as necessary */
    overflow: hidden;
    text-overflow: ellipsis;
}

fixed. see details here https://github.com/abantecart/abantecart-src/commit/f32d69ea1bc83c46afc404464b9d8a7a2bc7a9b0

Hi core devs,

i want to ask why does the second level breadcrumb is removed?

For example i open Home > Apparel & accessories > Shoes. the breadcrumb only shows Home > Shoes.

Please refer to the attached screenshot.

I test in a clean 1.4.0 installation. Both novator and default template are the same.

Hello,

Version 1.3.2 is outdated and requires an older PHP version, which you likely don't have. We recommend installing the latest version, 1.4.0

From what I am reading in this forum is there should be an extension that I could just turn off but my version 1.4.0  doesn't have that extension. I am using 'novator' theme.

Hello. The regular checkout is deprecated in 1.4.0
