how a drop down menu is populated

[dev_K]

Hello,

How can I see how the dropdown is populated?

In my catalog item I have this dropdown that gets populated with options:

Also, those options depend on the selected environment selected before:

However after checking the catalog item variables I see that for 'security zone' field it is a select box (and not a reference field as I would expect that will just fetch options from a table)

however, when i check the question choices there are none.

How can I investigate how the dropdown is populated??

The g_scratchpad object passes information from the server to the client, such as when the client requires information unavailable on the form.

Check the type specification. There you can select the table
