Hello. I have added a custom field to posts in a client site. This field is meant to add a relevant product code to a product suggested in the post itself. The field is storing the product (which is a custom post type) post id. Now, in wp-admin editors need to manually enter the post id. Is there any way to have editors choose a post from a dropdown listing posts? or have an ajax search performed when users type the post title? Any idea/sample?

Hi, unfortunately there is not currently an autosuggest feature to select a post as the value of a custom field. We are currently working on the next major release of Types and Views, which includes some big improvements in the way you link posts to other posts, and this issue is being addressed with those improvements. You can follow our blog for updates about these improvements:

For now, the post ID custom field is one manual approach we have to link posts in wp-admin. Another solution is to create many-to-many relationships between these two post types, where you can use autosuggest to select from post titles. Both these approaches have pros and cons. The custom field approach, as you have discovered, is tedious because it's not easy to select post IDs in the admin interface. On the other hand many-to-many relationships are easier to manage in wp-admin because you can use autosuggest features, but these many-to-many relationships can be less flexible as custom search filters or query filters.
