How to go about dropdown default value based on another dropdown?

I have the following dropdowns, now if I select test1 and then test11 in the second dropdown, when I change the first one to be test2, the second dropdown holds the old value and shows test11 although that's not a valid option.

 

 

<form version="1.1" theme="dark">
  <fieldset>
    <input type="dropdown" token="test">
      <label>Test</label>
      <choice value="*">All</choice>
      <choice value="test1">test1</choice>
      <choice value="test2">test2</choice>
    </input>
    <input type="dropdown" token="dependsontest" searchWhenChanged="false">
      <label>DependsOnTest</label>
      <fieldForLabel>$test$</fieldForLabel>
      <fieldForValue>$test$</fieldForValue>
      <choice value="*">All</choice>
      <search>
        <query>| makeresults
| fields - _time
| eval test1="test11,test12",test2="test21,test22" 
| fields $test$
| makemv $test$ delim=","
| mvexpand $test$</query>
      </search>
    </input>
    </fieldset>
</form>

 

 


I tried the <selectFirstChoice>true</selectFirstChoice> and default values but those didn't work. How can I go about this ?

EDIT: I tried using the "change" and "condition" and found out that the "dependsontest" token gets updated but the dropdown UI doesn't.

Here is what I was trying before, where the "dependsontest" token would get updated but the UI would show a stale value.

      <change>
          <set token="dependsontest">All</set>
      </change>

 

Here is what I am doing now and it updates both the token AND the UI

 

      <change>
          <set token="form.dependsontest">All</set>
      </change>

I think I found the underlying issue but not a solution for it. I used a "change" like richgalloway suggested and the actual token gets updated but the dropdown UI still shows a stale value.

As an untested idea, try adding code to unset the second token when the first one changes.

<form version="1.1" theme="dark">
  <fieldset>
    <input type="dropdown" token="test">
      <label>Test</label>
      <choice value="*">All</choice>
      <choice value="test1">test1</choice>
      <choice value="test2">test2</choice>
      <change>
         <unset token="dependsontest"/>
      </change>
    </input>
    <input type="dropdown" token="dependsontest" searchWhenChanged="false">
      <label>DependsOnTest</label>

Can this be done in Dashboard Studio JSON configuration?

This was interesting, I tried some variations of your approach but the old choice still stays
