Dynamic dropdown field options using another dropdown value

[ISP8055]

Hi there, 
Is there a way to create/display a dynamic dropdown using value selected from another dropdown?

For example of what I'm trying to do: 
Suppose I have 2 fields: Region and Server Name.

Region  Server

NY           A1

                 B1
                 X1

                 Z1

LA            A2

                 Y2

                  Z2

TO          A3

                B3

                 C3

So, the first drop-down gives the user option of selecting region : TO, NY or LA. 
User selects the region: NY,

then it should display a dropdown listing the name of NY's server names

and when the user selects a NY server: B1, then it displays the panel based on search for server: S1

hi @ISP8055,

Yes, you can use the first dropdown token in the second dropdown to filter results. Check this.

<fieldset submitButton="true" autoRun="false">
    <input type="dropdown" token="sourcetype">
      <label>Sourcetype</label>
      <fieldForLabel>sourcetype</fieldForLabel>
      <fieldForValue>sourcetype</fieldForValue>
      <search>
        <query>index=_internal | stats count by sourcetype</query>
        <earliest>-60m@m</earliest>
        <latest>now</latest>
      </search>
    </input>
    <input type="dropdown" token="host">
      <label>Hosts</label>
      <fieldForLabel>host</fieldForLabel>
      <fieldForValue>host</fieldForValue>
      <search>
        <query>index=_internal sourcetype="$sourcetype$" | stats count by host</query>
        <earliest>-24h@h</earliest>
        <latest>now</latest>
      </search>
    </input>
  </fieldset>

Hi there,

I tried your search syntax. However, when I select a option from the first dropdown list, the second dropdown doesn't let me select. Second dropdown is greyed out.

Hi, 

I did further troubleshooting and  found the issue with my search query. Your syntax helped.
Thanks.
