I have two lists:
The customer list is large -> >10.000 items. When i bind the customer via a lookup field to the Customer_Documents list in general it works, but it is not very user friendly cause of the large amount of items.
Is there a way to use something like SELECT2 or similar to filter/search for items within lookup column?
I need a way without programming, cause i am only able to use OOTB functions like JS, SPDesigner, WebParts etc.
