Sub menu showing with main menu in footer widget

Hello,

Page menu is my footer isn’t showing the sub-menu as a sub, instead, they are being shown with the main menu. Travel guides, photography, stories are sub-menu of the blog and should be shown under blog (the way they show in the main menu at the top of the page).

I want them to be shown like they do in the footer of Pinnacle theme home page (sub-menus as a proper sub rather than with the main menu). As shown below
