How to show/hide fields based off of selecting a list value not tied to a reference table (via UI policy)

[ServiceNow_Use2]

I have a custom list (Colors) that contains the choices Red, Green, and Blue.  
The Choice List Specification is set to "Dropdown with --None--"

There are three text fields that I would like to be displayed, depending on which color is picked (and ONLY when a color is picked).  The logic is as follows: 
When Red is selected in the list, Text1 becomes visible.
When Green is selected in the list, Text2 becomes visible. 
When Blue is selected in the list, Text3 becomes visible.  
All text fields can be visible at once, but if a color is removed from the list, the corresponding text area needs to no longer be visible.  

I have tried to configure this logic via a UI policy, but every time I add a value to the Conditions area, (i.e. Red, Green, or Blue), the value gets wiped out.  When i try and click on the little search icon next to the field, I get "The page you are looking for could not be found."  Am I not putting the correct value into the conditions field? Or, what am I missing to get the logic to work the way that I want? Any help would be greatly appreciated.

Hi,

I just did this in my PDI and have no problems. So I'll explain what I did and try and provide some screenshots for you. To be clear, this is for a list collector...not a "choice list". So just want to make sure we're on the same page here.

-So I made a table, not extended from anything, added a column called colors, set the display field to the Color, three entries: Red, Green, Blue.

-Created a catalog item with 4 variables: 1 - List Collector, 3 - Single Text fields (named them Text1, Text2, Text3).

-Created 3 UI Policies, one for each color. I'll show a sample of one, but it's literally the same thing for the other 2 except the color is different, and the text field that shows is different, but it all coincides with what you wrote above:

-I set the order for the 3 UI polices to: Red UI Policy 100, Green UI Policy 200, Blue UI Policy 300.

-I tested the item which starts out like this:

I select Red, so now the form looks like this:

-I'll select all 3, so now it looks like this:

-I'll remove...say...the middle one in your list there which is Green...so now the form looks like this:

Hopefully this helps you solve your issue.

If you're doing it another way, I think my method will still get you to where you want to go, you just need to ensure you make 3 separate UI policies.

Hello @Allen Andreas ,

I've a requirement for change request form as mentioned below:

On Change Request form dropdown field is there:

• "What type of location is affected" (Mandatory)
  • Enterprise Wide
  • Region
  • Country
  • Select Locations

Then we have a list Collector reference from cmn_location table.

So here if we select the dropdown as a country then in the list collector I need to show only country column. If we select Region then in the list collector only region column must be available.

Is there any way to fulfil this?
