Menu path route:<nolink> breaks style

Same thing in 8.x-3.x-dev.

This menu item is "span". If I change it manually to "a" it will be fixed.

Drupal Bootstrap theme assume that there will be link: .nav > li > a

I know it, but what should we do?...

Fix it in your subtheme wherever your menu styles go. For example,

.nav > li > a,
.nav > li > span {
  // Menu item styles
}

Thank you @imclean, but this is a workaround, not a solution. I have no idea, how this case not has been resolved for years :) I'll create a patch today.

Cache rebuild required.

This project no longer adds styling components. It, instead, does that in https://github.com/unicorn-fail/drupal-bootstrap-styles.

Regardless, I doubt this is necessary. We should be able to just check for <nolink> and then add the navbar-text class to it accordingly.

Works, but there are some bugs:

1. Text color is different.
2. Background color doesn't changes on hover.
3. Cursor doesn't changes on hover.

This is because in css uses tag (a), not class.
E.g.

.navbar-default .navbar-nav > li > a {
    color: #ffffff;
}

Want should I do?

1. Text color is different.
2. Background color doesn't changes on hover.
3. Cursor doesn't changes on hover.

This is because in css uses tag (a), not class.

That's because when you use <nolink> it shouldn't output a link (hence the name).

So yes, the text, bg and cursor are different... as they should be.

If you want it to behave like a link, then populate it with a real link. Like to the landing page for that dropdown, presumably, so users without JS (who wouldn't see the dropdown) can get to the sub-menu links that way.

The code is already designed to handle dropdowns so it opens it instead of navigating to the actual link (this is the way Bootstrap is designed).

Whoops. Wrong issue.
