How to create a dynamic drop-down based on field?

Hi,
I wan to create one drop-down based on field (this field is host - IP address). So I want to find all hosts on port 4545 (source="tcp:4545") and put them (their IP addresses) in the drop-down menu. Once the user has selected one of the IP addresses from the drop-down menu, I will call this search string: source="tcp:4545" host="selected_ip_address".

My question is how can I create a dynamic drop-down menu based on host field? I need help only for dynamic filling drop-down menu - if it is possible.

Thanks,
Klemen

      </search>
      <fieldForLabel>host</fieldForLabel>
      <fieldForValue>host</fieldForValue>
    </input>
  </fieldset>
  <row>
    <panel>
      <event>
        <title>foo</title>
        <search>
          <query>index=_internal source="tcp:4545" host=$ip$</query>
          <earliest>0</earliest>
          <latest></latest>
        </search>
        <option name="count">10</option>

You can also use this for your dropdown search (may be faster)

| tstats count WHERE index=_internal source="tcp:4545" by host | table host

Great, thank you. It is very easy, but I am just a beginner in Splunk.
