@smarie I'm not sure what you are mean by "custom post does not appear in my insert merge tag dropdown". Are you referring to custom post types? If so, that isn't going to appear in the "insert merge tag" drop down. Only Gravity Forms merge tags related to your form and fields will appear in the "insert merge tag drop down".
To use the Content Template feature of the Post Body field you need to edit your form, then edit your Post Body field. There will be an option on that field to enable the content template, check that box to enable it.
When you enable the content template it will display a textarea field that you can use to configure the content template. In that textarea you can insert text, HTML or merge tags to format the content the way you want it to be created. WHATEVER you configure in the content template is EXACTLY what will be used to create the post body when the post is created.
Documentation for the content template option can be found here:
If what you are trying to do is create a custom post type, that isn't something Gravity Forms does out of the box. You would need to use the 3rd party Gravity Forms Custom Post Types Add-On to do something like that. You can find it here:
