How to see selected option from drop-down in custom field on the default screen of issue?

[Ivan_Kann]

Hello community team,
I need a support with the following:

I have a list with 15 options (the options are contractors).
When a user comes up to the specific status, the user should select the contractor from the list.
The user can select a contractor from the pop-up window with a dropdown field.

When a contractor is selected, the contractot should be displayed in custom field (say, view only text field).

- A user comes up to the status "Select Contractor"
- A user hits the status
- Jira shows a pop-up window with drop-down field
- A user hits drop-down
- A user selects contractor_AXY
- A user closes pop-up
- Jira displays contractor_AXY in custom field on default screen of issue

Please help to make it?

The custom field is already created. 

The problem is to show the selected contractor into the field.

Hi @Ivan_Kann  You have to add the transition screen for this. 

When user is moving to Status Contrators >add transition screen on this. In that you can add this dropdown custom field.

if you want to make field mandatory on transition screen> go to validator >select field required

Add same field on view issue screen

Hi, @Vikrant Yadav 

Yes, I have already created a pop-up window with drop-down.
A user can select a contractor from the list.
Also I created a custom field (view only) to display a contractor's name.

But the problem remained that the contractor does not appear in the field.

I assume there needs some script to make it.

Hi @Ivan_Kann  Contractor is dropdown field right ? 
one view screen you want the same Contractor field ?

where it's not appearing on view screen or transition screen ? 

is it possible for you to share the screenshot, then it might be easy to understand for me. 

Thanks
