Hi @arr1127 :
Could you describe "display options related to that" in detail ?(In what control are these options? Which data source does its data come from? What does it have to do with the date selected by the user? In what control does the user select the date? What is the data source of the control?What is the relationship between the date selected by the user and the options of another control?)
I assume that the user selects a date through a dropdown(DropdownA), and another dropdown control(DropdownA), provides different options according to the date selected by the user.The key is to use the selection of DropDownA to filter the data source of DropDownB.I'v made a test for your reference
1\DropdownA
Items
["Date1","Date2","Date3"]
2\
Item
Switch(
DropdownA.SelectedText.Value,
"Date1",
[
"Option1",
"Option2"
],
"Date2",
[
"OptionA",
"OptionB"
],
"Date3",
[
"Option!",
"Option@"
]
)

Best Regards,
