How to clear selected Dropdown value and reset it to default value on selection of another dropdown?

[Digvijay]

Hi ,

Below is my dashboard :

I want to clear selected Dropdown value for dropdown "Operation" and reset it to default value on selection of another dropdown named "Method" .

My dropdown population code as below :

<input type="dropdown" token="token_method" searchWhenChanged="true">
<label>Select Method:</label>
<fieldForLabel>METHOD</fieldForLabel>
<fieldForValue>METHOD</fieldForValue>
<search>
<query>| makeresults | eval API="party_interaction_rest",METHOD="Alle,GET,POST" |
append [| makeresults | eval API="ticket_mgmt_rest",METHOD="Alle,GET,POST,PATCH"] |
append [| makeresults | eval API="customer_management_rest",METHOD="Alle,GET,PATCH"] |
append [| makeresults | eval API="agreement_management_rest",METHOD="Alle,GET"] |
append [| makeresults | eval API="product_order_rest",METHOD="Alle,GET,POST,PATCH,DELETE"] |
append [| makeresults | eval API="product_inv_rest",METHOD="Alle,GET,POST,PATCH"] | eval METHOD=split(METHOD,",")
|mvexpand METHOD| table API METHOD | search API="$token_service$"</query>
</search>
<change>
<condition value="Alle">
<set token="token_method">*</set>
</condition>
</change>
<default>Alle</default>
<initialValue>Alle</initialValue>
</input>
<input type="dropdown" token="tkn_OPERATION">
<label>Select Operation:</label>
<fieldForLabel>OPERATION</fieldForLabel>
<fieldForValue>OPERATION</fieldForValue>
<search>
<query>| inputlookup append=t REST_OPERATION_LOOKUP.csv where API="$token_service$" METHOD="$token_method$"

@bowesmana ,

Thanks for the solution , now my reset part is working fine.

[bowesmana · Accepted solution]

In the change conditions for the METHOD dropdown add a reset to the operation token (note the form. prefix)

      <change>
        <condition value="Alle">
          <set token="token_method">*</set>
          <set token="form.tkn_OPERATION">*</set>
        </condition>
        <condition value="*">
          <set token="form.tkn_OPERATION">*</set>
        </condition>
      </change>

Something along the lines of the above, depending on your config

This solution is good.
But after selection, if refresh the dashboard you will lose the selection.

Any help please
