Hi @stephanieliy,
First of all sorry for my bad English.
I’ll explain a little bit
Imagine you have 100+ of campaign to create, and every campaign has it own details page, the details page has gallery, video, images and description.
You need to create each 100+ campaign a details page.
But, If you’re using WordPress>Post, you just need to create ONE template page to display 100+ Post, you don’t need to create 100+ pages
So if this dynamic tags option is available in GiveWP widget, I can make every Campaign Details Page has it own GiveWP Form Button ID. with ONE template page only.
A video explain what is dynamic tags: https://www.youtube.com/watch?v=Ki5XBlid67A
