Does anyone have code to validate that an drop down is alpha?

Hi,
I’m looking for a simple way to validate the above. I know it can be done in Selenium, but was looking for a more concise way to do in Katalon. Seems like a common validation.
All I want to do is validate that the values in a drop down values are in descending alpha order. And if it’s not to throw an error.
ex.
findTestObject(‘dancestyle_dropdown’)
