I am looking for a solution where I do have a field(textbox) in NINTEX form which need to lookup into another SharePoint list(more that 15000 records) and populate the records matching with what I entered in textbox.
1. On form I do have field called supplier which is textbox.
2. I do have another master list of supplier which contains more than 15000 records.
3. I need functionality where I can type in textbox(supplier) and it should show values from the supplier list(Supplier_All).
Currently I manage to achieve this using javacript and dropdown in the form but its not working for more than 5000 suppliers.
Can you please suggest how I can solve this problem?
