Dropdown select from a related record

Hi everyone,

I am building a table in my project management app to evaluate vendors.  In the vendors table I have a multi-select field with a list of services vendors provide.  As the vendor is added to the database the user can select what services they provide (it is not a separate table).

I have a relationship with each vendor has many vendor evaluations.

On the vendor evaluations table I want to have a field that displays the list of services that particular provides as a dropdown so the user can select which services they provided on this project.

Any ideas on how to do that?  I have a lookup field set but it shows all of the services the vendor can provide.  Now I want to set that essentially as a multi-select to clarify what they actually did do on the project.

Thanks in advance!

  • The only way to do that is if the list of possible Services is setup as a separate table and then you have a Child table that is a Many to Many between Vendor and Services, called Vendor Services for this example. You can then create a relationship between Evaluations and Vendor Services and have the drop-down for Vendor Services setup as a Conditional Drop-down based on the selection in Vendor.

      Hmmm and I would imagine trying to change that with existing data is a very manual process......  We have about 200 records with services already.  Or can I use that feature to create related table to create column and will it maintain the link?  I dont think that would work for the many to many scenario but that gets me half way there
