How do I add Topics page for menu we use NopCommerce 3.4

If you use the version 3.40.
To add an item to the main menu you should edit the TopMenu.cshtml view.

For example, if you want to add link to the shipping info topic add the following line

<li><a href="@Url.RouteUrl("Topic", new {SeName = Html.GetTopicSeName("shippinginfo") })">@T("ShippingReturns")</a></li>

before

@Html.Widget("header_menu_after")

and

@Html.Widget("mob_header_menu_after")
