Dropdown Options

Ignition

Lets say I have a dropdown - the options are bound to a named query that returns 3 columns. I have columns ID, x, y. Is there a way to have x,y show up on each option together?

You'll need a transform of some kind. Vision or Perspective?

Why not do a separate named query for the dropdown and use the concat() function to create the labels? e.g.,

SELECT ID as value,
       CONCAT(x, " ", y) AS label
FROM ...

Then bind the dropdown's props.options to that named query.

Going the pure Binding/Transform route:

# This example uses an incoming JSON query value with known columns of "id", "name", and "quantity".
# Adjust for your scenario. Remember to adjust for potential TypeErrors.
def transform(self, value, quality, timestamp):
	options = []
	for option in value:
		options.append({"label": " ".join([option.name, str(option.quantity)]), "value": option.id})
	return options
