I actually figured out the issue. I needed to add the "Post Content" elementor widget to my Single Post Template in order for Toolset to inject the edit post form.
I do another unrelated question.
Is there a way to populate hidden fields in the Toolset form before it is submitted? Either with javascript or another way?
I implemented code similar to that, and I can see the hidden fields "value" is updating as expected in the HTML, but after I submit the form, the post still has its old value.
Maybe I can explain what I want to do.
I am trying to use Toolset custom post field values inside an Elementor single post template.
Certain widgets have both a "Dynamic Text" and a "Dynamic Link" input. I want to use the same custom field value for both. But if the Custom Field type is text I can't use it in the Dynamic Link field and if the custom field type is URL then I can't use it in the dynamic text field.
So I am creating a duplicate version of the custom field so that I can autopopulate it with the same value as entered in the form and I have the same data as both plain text and URL field
