Hi Tori,
Thanks for reaching out and thanks for using BoldGrid with BoldGrid Post and Page Builder for WordPress!
WordPress has a built in functionality that allows you to pin post to the top of your blog. In order to accomplish this visit the Posts page from your dashboard, hover over the post you’d like to add to the top of your blog and click Quick Edit.
You’ll see a check box that reads: “Make this post sticky“, check that and the post will begin to display at the top of your blog.
I hope this helps. Please reach back out if you have any other questions for us.
