We are trying to connect Ninja form submissions (post type = nf_sub) with Toolset created post type named as Rule. But the nf_sub post type is not visible in the Toolset Type dashboard or relationship wizard area.
Is it possible to setup a relationship in between "nf_sub" and "rule" post type using code or Toolset?
We tried the toolset_connect_posts hook but this returns the "The relationship does not exist" error which is fair because we never created it.
So, I am wondering if we can achieve one of the following?
1. Create/register/establish a relationship between nf_sub and rule post type? (check image1.png)
2. Or if it's possible to make nf_sub visible in toolset type sections so we can use it just like standard custom post type?
