How to dynamically fill in a dropdown?

Path Finder

Hi all,
We have some custom JSON data getting into Splunk. We're also creating some dashboard with this data. Everything is working great, except for the dynamic drop down.

In our data, (below), we have JSON coming from two different devices, one has a powerdata of branch1 and another has a powerdata of branch1 and branch2.

What I would like to do is to show or display all selections to the maximum reading like (1,2,34,5,6,7,8 and so on) in powerdata for each branch current in the dropdown.

FYI, look similar to the below link, but I would like to rad the data from powerdata for each branch instead of from the plugcount.

Looking forward to your help.

Here is the JSON sent to Splunk

     assettag:   VMR-8HS20-2    
     ats:    0  
     branchcount:    1

     plugcount:  8  
     powerdata: [   [-] 
        {   [-] 
         branch1:   [   [-] 
            {   [-] 
             current1:   1.90   
             voltage1:   120.00 
            }
