How to remove automatically assigned Joomla classes?

Question

css

I want to remove the extra classes that Joomla assigns.
Now stands

<ul class="nav menu main_menu" id="mainmenu">
<li class="item-107 current active"><a href="/ru/o-nas">О нас</a></li>
</ul>

Here you can see that the module assigned additional nav and menu classes to my layout . Is it possible to remove them? I don't need them at all, since all the styles are already registered on the main_menu class .

Answer 1

I don't think they will interfere in any way.

Answer 2

You need to redefine the template of this module, creating the layout of the module as you like. Good and plentiful googling .
