Drop-down values

Hi,

Here I am having one dropdown if I select Exclusion there then category,type and add exclusion button will be visible. But when I click on add exclusion button in next category and type are getting duplicated I dont want that I want to select other exclusion and Type differently . How can I achieve it?

Code:

local!set: if(a!isNotNullOrEmpty(local!exclusionList),
index(local!exclusionList.set,1,{}),
{}),

saveInto: {
a!forEach(
items: local!exclusionList,
expression: a!save(
local!exclusionList,
append(
local!exclusionList,
a!map(
set: local!set,
coveragetoRoleId: ri!basCoverageToRole['recordType!{33c2cbea-4c4e-4288-9d10-d6107f847a76}UWG Coverage To Role.fields.{c8b1b4ee-b5f4-494d-bcf3-763d83073e71}id'],
standardUWSupportCodeRefId: null,
exclusionText: ""
)
)
)
)
},
