Thank you, It worked. But, I am looking display secondary menu after certain content of that page. Like I showed in previous example. Also when user selects menu option, I wanted to stay in the same page and display the blog posts related to that category.
Exactly same as example show earlier.
Regarding Cards display, what is the other alternate to display blog post? is there any suggestion?
I wanted to display blog posts in cards display even in category pages or tags
Could you pls help on this?
If you were using the GP Themes archive templates instead of static pages then you would be able to use Categories in your secondary nav, and simply set the display rules for the navigation to Post Category Archive > All Categories.
But it cannot be done with static pages.
If you want to revert to using the Theme templates we can look at some CSS to style the posts to look more like cards.
