The general answer is "no", but it depends on what you are trying to achieve.
Splunk is not a database, in that sense, so there is no such thing as "editing" the results of a Splunk search.
Given a reasonable use case, you can also create screens and forms that can change the contents of the indexes, for instance by inserting or deleting records. That is definitely not the normal architecture of Splunk, with the exception of certain workflow methodologies. More commonly you might have a way to change the contents of lookup tables.
If you explain more fully what you are trying to accomplish, then we can help further.
I'm getting the data from a kv store and what I'm triying to achieve, is that the user could modify some of the fields. In my case I have 7 columns in the kv store and the user can only modify the last three of them. The problem is that the table and components, appear after the load of the page and the TableElement, so I don't know how to get that table elements.
@ragnaroksg, following Splunk Dev Site talks about deletion of a KV pair from collection after which corrected KV Pair can be added. See if this fits your needs: http://dev.splunk.com/view/SP-CAAAEZX
@ragnaroksg, if possible please add the solution as an answer and accept the same to mark this question answered and for other’s reference.
