Splunk Search

Dropdown values from lookup

Im having a lookup table which consist of applicationid,applicationname,hosts. For single application I have many hosts.
So I tried with the below
appid,appname,host
APP123,ABCDE,host1;host2;host3
APP234,CDDSD,host4;host5;host6

I want to have two dropdowns in my form. One for application another one for host.
I want to populate the hosts one by one in dropdown corresponding to application. I tried with the delimiter ";".
However no luck. Is there any possible solution or should I go with one by one for each host in lookup 😞

    <label>ABC</label>
    <fieldset autoRun="false">
            <input type="time">
                    <label>Select Time</label>
                    <default>Last 15 minutes</default>
            </input>

            <input type="dropdown" token="appid">
                    <label>Select appid</label>
                    <populatingSearch fieldForValue="appid" fieldForLabel="applabel">
                            <![CDATA[ | inputlookup abc.csv |dedup appid,appname | sort appid,appname | eval applabel=appid + "-" + appname ]]>
                    </populatingSearch>
                    <default>*</default>
  <choice value="*">All</choice>
            </input>

            <input type="dropdown" token="host">
                    <label>Select host</label>
                    <populatingSearch fieldForValue="host" fieldForLabel="host">
                            <![CDATA[ | inputlookup abc.csv  | search appid=$appid$ | makemv delim=";" host | fields host ]]>
                    </populatingSearch>
                    <default>*</default>
  <choice value="*">All</choice>
            </input>
    </fieldset>

Try this,

Populate Appid search,

| inputlookup abc.csv |dedup appid,appname | sort appid,appname | eval applabel=appid + "-" + appname

Populate Host based on Appid search, [ Assuming you have ";" as your delimiter in host field ]

| inputlookup abc.csv  | eval host=split(host,";") | mvexpand host | search appid=$appid$ | stats count by host  | fields host

Hope this will help you,

Cheers!
