How to populate drop-downs with static fields based on the value chosen from the previous drop-down?

[alan20854]

Hi,

I have three drop-downs for my dashboard, and I already have a list of all the potential values for each of the three drop-downs. However, I would like the second and third drop-downs to only contain a set of the values based on the value chosen from the previous drop-down.

What is the best way to do this?

Thanks

What I would do is to create a lookup table file using these mappings and then use that lookup table to query and filter.

Create lookup table - http://docs.splunk.com/Documentation/Splunk/6.4.1/Knowledge/ConfigureCSVlookups
Say with Name dropdown_values.csv with following field/data

field1,field2,field3
PCL,EIR,PRCS_EIR
PCL,EIR,RTRV_EIR
PE,PE_WS,CREAT_NRLMT
PE,PE_WS,UPDT_DEMOGRAPHIC
...and so on

Write your dashboard's dropdowns like this

<input type="dropdown" token="token1">
   <label>Field 1</label>  
   <search>
     <query> | inputlookup dropdown_values.csv | stats count by field1 | table field1 </query>
   </search>
   <fieldForLabel>field1 </fieldForLabel>
   <fieldForValue>field1 </fieldForValue>
</input>
<input type="dropdown" token="token2">
   <label>Field 1</label>  
   <search>
     <query> | inputlookup dropdown_values.csv | search field1="$token1$" | stats count by field2 | table field2 </query>
   </search>
   <fieldForLabel>field2</fieldForLabel>
   <fieldForValue>field2</fieldForValue>
</input>
<input type="dropdown" token="token3">
   <label>Field 1</label>  
   <search>
     <query> | inputlookup dropdown_values.csv | search field1="$token1$" | stats count by field3 | table field3 </query>
   </search>
   <fieldForLabel>field3</fieldForLabel>
   <fieldForValue>field3</fieldForValue>
</input

To be able to dynamically load the options in 2nd and 3rd dropdown, you would have to use dynamic population method for those two dropdowns. Post the sample values for dropdowns and mapping of the dropdown values (upon selection of what values, which value should be shown).
