How to edit my XML so clicking on a radio button automatically populates drop-down values while not retaining the previous value in the drop-down?

[rupandit18]

I am working on a use case where I have 3 radio buttons ( say 2001, 2002 and Today) and one drop-down. Clicking on the 2002 radio button should display all the movie releases occurred in that year ( let's say MovieA , MovieB , MovieC ). Now, in the drop-down, select MovieB so now drop-down displays MovieB. Now, click on other radio button, let's say, 2001. So at this time, the drop-down should populate all the releases that occurred in the year 2001, and it should not retain the previously selected value in the drop-down which in this case would be MovieB. I am fine with having one default value ( which would show up in the drop-down, something like "Please select Value", and when clicking on the drop-down arrow, you can see all movies of that year ) for all radio buttons as long as it does NOT retain the previously selected value in the drop-down.

My code is attached below.

< fieldset submitButton="false">
    < input type="radio" token="event_date_type2" searchWhenChanged="true">
      < default>Today < /default>
      < earliest>-24h< /earliest>
      < latest>now< /latest>
      < populatingSearch fieldForValue="event_date_type2" fieldForLabel="event_date_type2">
        < ![CDATA[| inputlookup file.csv | FIELDS event_date_type2 |
        eval event_date_type2 = substr(event_date_type2,0,4) | dedup
        event_date_type2
        |where event_date_type2!=0 | append [ inputlookup
        Events_Lookup_20141001.csv |stats count |eval event_date_type2="Today"
        | FIELDS event_date_type2] ]]>
      < /populatingSearch >
    < /input>
    < input type="dropdown" token="field2" searchWhenChanged="false">
      < label>Select a Date</label>
      < search>
        < query>|inputlookup Events_Lookup_20141001.csv  | where like(event_date,"%$event_date_type2$%")  | append [ inputlookup Events_Lookup_20141001.csv |stats count |eval event_date_type2="%$event_date_type2$%" | eval title="Today"| eval latest_timestamp =strftime(now(),"%s")       | eval earliest_timestamp = now()-86400 ] | where like(title, "%$event_date_type2$%")
     < /query>
      < /search>
     < fieldForLabel>title< /fieldForLabel>
      < fieldForValue>title< /fieldForValue>
      < default>Please select Value < /default> // This is default value to be shown un in dropdown as soon as radio button pressed.     
      < change>
        < set token="field2.earliest">$row.earliest_timestamp$< /set>
         < set token="field2.latest">$row.latest_timestamp$< /set>
      < /change>

Truly appreciate your help on this fix. Please let me know what am I missing here.

Thank you.

I'm not sure this can be done without Javascript.

In Javascript, you can simply listen to a change of the radio buttons and in that case set the selection of the dropdown to the standard selection. If you are interested, you might want to have a look here and here.

By the way, if you're looking for a way to "clear" the dropdown, you should put something like "Any" as label and use * as value; in most search scenarios, this should have the effect of "nothing selected" on a search (i.e. index = foo movie_title=$dropdown$ with $dropdown$ replaced by * does not filter anything besides events whithout the field movie_title). That way, the user doesn't even have to select something from the dropdown in order to see results.

Thank you for your response. Yes, I did try that too but did not see expected experience. However, was able to handle this through XML itself. No need of JS.
