I created a child form, and I set it already pre-defined the parent.
But when user on the front end submit this form, it won't connect to the parent post when I check it in the dashboard.
[cred_field field='@business-review.parent' class='form-control' output='bootstrap' select_text='--- not set ---' required='true' value='[wpv-post-id]']
It only work when the user choose the parent post themself, but I don't want that.
During troubleshooting, I noticed that the form to write a review was set to show in a popup, which was affecting the initialization of the "autocomplete" (select2 script) of the relationship field.
