Creating the Instagram page
On your WP Dashboard, navigate to the Pages tab.
Create a new page and name it “Instagram” or however you would like to name your Instagram page.
Under “Page Attributes” assign an Instagram Template to this page, and click Publish.
Creating a set of menu for the Instagram page
Navigate to Appearance >> Menus
Click “Create a New Menu”
Enter a name like “Instagram menu” or however you want to name it, and click “Create Menu”.
Add your set of links to this set of menu (you can always edit it later), and save.
Adding items to your Instagram page
Lastly, go to Appearance >> Widgets.
Drag a “Navigation Menu” widget item to the Instagram widget area.
Open the Navigation Menu tab, and select the “Instagram menu” that you have created earlier.
You can also add more widget items into this widget area. For instance, I added User Profile, Social Buttons and Recent Posts.
That’s all and your Instagram page is ready!
