Hey there! Just a few days back I found the PayloadCMS and it seems like a nice tool - I started working on a project, but I'm clearly not very versed in it yet.

Now, I do have a problem regarding the select functionality - the situation is the following. I have the following data structure:

- Sellers: id (uuid), name (string), ...

- Products: id (uuid), name (string), ...

- SellerProducts: id (uuid), seller (relationship), product (relationship), ...

- SellerProductPromotions: id (uuid), sellerProduct (relationship), ...

Now, if I want to create a new SellerProductPromotions entry, the autocompleted select will by default return the ID for SellerProducts for the label, but that's clearly not viable.

How would I approach that? Seems that admin.useAsTitle only accepts a string, but I would need something like "(entry) =>

${entry.product.name} (${entry.seller.name})

" (including the filter search for that). Is that possible to do with PayloadCMS?

Hi
@269130158982561794
- you could create a virtual field which is a common solution we use for creating dynamic titles. Read more about them here
https://payloadcms.com/blog/learn-how-virtual-fields-can-help-solve-common-cms-challenges

Essentially you could add another field that combines your entry.product.name and entry.seller.name and use that as your title. You can also add a beforeChange hook to remove the value from your database so it is fully virtual.
```
{
  name: 'title',
  type: 'text',
  admin: {
    hidden: true, // hides the field from the admin panel
  },
  hooks: {
    beforeChange: [
      ({ siblingData }) => {
        // ensures data is not stored in DB
        delete siblingData['title']
      }
    ],
    afterRead: [
      ({ data }) => {  
        return `${data.product.name} ${data.seller.name}`;
      }
    ],
  },
}
```
Something along the lines of this 👆 Hope this helps!
