Hello @Hamadaltaf - it sounds like you might be using Add-on Builder - which I do not believe supports this case with the setup screen WYSIWYG builder. You might be better of constructing a setup screen manually, which will allow you to have the sort of control over the setup experience that you want. Here's a fairly detailed example on building a setup view from scratch.

Also keep in mind you will likely be using different parts of the Splunk REST API to access things like passwords and potentially searches and related results, lookups, KVStore collections, etc.
