-TICKET MANAGAMENT

2.SELECT OPERATION

-this second dropdown needs to be populated based on first one

a. If API = PARTY INTERACTION 

then values here -

<choice value="LISTTROUBLETICKETS">LISTTROUBLETICKETS</choice>
<choice value="RETRIEVETROUBLETICKET">RETRIEVETROUBLETICKET</choice>
<choice value="CREATETICKET">CREATETICKET</choice>
<choice value="UPDATETICKET">UPDATETICKET</choice>
<choice value="RETRIEVETICKETTHEME">RETRIEVETICKETTHEME</choice>
<choice value="GETINBOXDETAILSFORUSER">GETINBOXDETAILSFORUSER</choice>

b.If API=TICKET MANAGAMENT

<choice value="*">Alle</choice>
<choice value="LISTPARTYINTERACTIONS">LISTPARTYINTERACTIONS</choice>

You should try something like this.

<fieldset submitButton="false">
    <input type="dropdown" token="tkn_API">
      <label>API</label>
      <choice value="PARTY INTERACTION">PARTY INTERACTION</choice>
      <choice value="TICKET MANAGAMENT">TICKET MANAGAMENT</choice>
    </input>
    <input type="dropdown" token="tkn_ OPERATION">
      <label>OPERATION</label>
      <fieldForLabel>OPERATION</fieldForLabel>
      <fieldForValue>OPERATION</fieldForValue>
      <search>
        <query>| makeresults | eval API="PARTY INTERACTION",OPERATION="LISTTROUBLETICKETS,RETRIEVETROUBLETICKE,CREATETICKET,UPDATETICKET,RETRIEVETICKETTHEME,GETINBOXDETAILSFORUSER
" | append [| makeresults | eval API="TICKET MANAGAMENT",OPERATION="LISTPARTYINTERACTIONS,RETRIEVEPARTYINTERACTION"] | eval OPERATION=split(OPERATION,",")
|mvexpand OPERATION| table API OPERATION  | search API="$tkn_API$"</query>
      </search>
    </input>
  </fieldset>
