dyanmic custom checkout field

it would be great so that that custom checkout field have select option and all the options are dynamic coming from relational, or object field or any other dynamic field. This will be totally new in the wordpress.

Example: {

There is a custom post type “stores” having some acf field. There is “user field” to select users assigned to “stores”

There is another custom field “object field” with post type set to “stores” and select multiple turned on. This field is assigned to “edit users”

Both user field and object field are bidirectional.

Example use case: This website only sells to retailers. if buyer has multiple stores and he needs to select that store he is assigned to through a dropdown select field (which is dynamically getting related stores for the logged in users), he/she want to order for so that products will be directly delivered to that store. buyer can select only one or multiple option as per restriction set by the seller.

When the order will be placed, the seller will get all the contents of selected store with order details…

}

Currently it’s possible only with custom php functions and css…

I have tested tons of plugins and none of them are able to do so, specially with divi… You can make it as a seperate plugin with some common features already in marketplace.
