Hi Saguaros!
Yes its custom module. But it works on t4 framework built-in nav-tabs.
The question is why it work like anchor link? What i am missing... Maybe its need some class or something. Can you help? Thanks.
<ul class="nav nav-tabs" role="tablist">
<li class="nav-item flex-fill">
<a class="nav-link" href="#stats_yakutia" role="tab" data-toggle="tab" aria-selected="false">
РС(Я) </a>
</li>
<li class="nav-item flex-fill">
<a class="nav-link" href="#stats_russia" role="tab" data-toggle="tab" aria-selected="false">
Россия </a>
</li>
<li class="nav-item flex-fill">
<a class="nav-link active" href="#stats_world" role="tab" data-toggle="tab" aria-selected="true">
Мир </a>
</li>
</ul>
