Hello there,
I need to set as a default always the second element of my list values, the value can change but I need to take always the second one.

How can I make that?
There's a way with javascript?

Thank you.

Marzia.

@marziaolla, Try the following Run anywhere dashboard example. It uses post-processing to identify the second value in the dropdown and sets the same as a token for default value.

PS: If the search for Dropdown returns only one result, the same will be set as default value. Also in case the Search does not return any results, I have used Static All option to be set as default value.

<form>
  <label>Second Value in the list</label>
 <!-- Your Search to populate the second item from the list should go here --->
  <search base="baseComponentSearch">
    <query>| head 2 | tail 1
    </query>
    <done>
      <!-- In case the Search does not return any results Static Option All should be selected -->
      <condition match="$job.resultCount$==0">
        <set token="tokDefaultSelectedComponent">*</set>
      </condition>
      <!-- Set the token using Search Event Handler's default token result.<yourFieldName> -->
      <!-- If the Search returns two or more results 2nd result will be selected -->
      <!-- If the Search returns only one result, the same will be selected -->
      <condition>
        <set token="tokDefaultSelectedComponent">$result.component$</set>
      </condition>
    </done>
  </search>

Any specific reason for it? Can you move the 2nd element in the first position (at populating search level) and then set the first element (which was 2nd element before) as default?
