Hello!
I need to create a data entry form that will limit dropdown menu choices based on the selection made in another field. I am looking at the possibility of establishing nested lists to define the hierarchy of options, but so far I'm not succeeding in creating an interactive drop down menu.
Is nested lists the right approach? If not, is there another way to do this?
Here's the example. Imagine I have a table that has 30 birds and 20 fish in the records.
In question 1 I want the user to be able to select "bird" or "fish", and then in Question 2 I only want the 30 birds or 20 fish to show in the species selection box, depending on what was chosen for Question 1. (In reality, I have an intermediate grouping level, and many more species than 30 or 20.
