Problems Using The Post Data Form Field

I am in the process of building a food blog web site at https://www.winthropiga.com.au.

The site is for the use of friends and family to share recipes, and I would like them to be able to submit recipes from the front end of the site without actually logging in and becoming WordPress users.

I have constructed a form with Forminator using the Post Data field, and have duplicated that field to make separate sections for recipe title, Ingredients, instructions, recipe notes and nutrition information etc., as well as post categories and tags.

I was under the impression that this would result in one draft post with all the uploaded information.

However it has actually resulted in a several draft posts – i.e. one for each section of the form.

I have several questions:

1.Is there any way to make the information on my form appear in one post on the back end, with the category and tag(s) that have been selected?

I appreciate that the information for all these sections could be entered in one “content” field, but I doubt that my end user audience will have the formatting skills to be able to separate the information into headings and paragraphs.

2.I have added drop down lists of categories and tags, but It appears that only one of each can be selected.

Is there any method available to select multiple categories or tags?

3.I have built my recipe post template using the Elementor and Advanced Custom Fields plugins.

Is there any way that the information entered on a particular section of the form (e.g. ingredients) can be routed directly to the appropriate custom field for the template, rather than just remaining as part of the post content?

The form can be accessed by way of a popup link (constructed with Hustle) in the right hand sidebar on the home page under the heading “Submit Your Own Recipe”.

The site is in the early stages of construction, with a lot of dummy content, and is not available to the general public as yet.

I would appreciate any assistance, and I can arrange for back end access as an Administrator if required.
