How to clear the old values of a multiselect input when I change the value on another drop-down in my Simple XML dashboard?

sjain135 — Tue, 28 Jun 2016 12:33:25 GMT

I would like to clear the old values of a multiselect input when I change the value on another drop-down. Actually, when I change the value in first drop-down, then the multiselect value does not clear the already selected value. It is taking the new values, but due to old selected value, the result in not coming as expected.

Does someone have any solution for this? I am using Simple XML in dashboard.

I found out this answer helpful:

[https://answers.splunk.com/answers/218751/selectfirstchoice-not-working-in-dynamic-dropdowns.html]

The above link did not explain it clearly.

In your drop-down Simple XML, unset the multiselect token. Make sure you specify "form. your-token-name" in the unset tag:

   <change>
        <unset token="form.my_id_name_multiselect"></unset>
      </change>

Full code

<form>
<fieldset submitButton="true" autoRun="false">
    <input type="dropdown" token="my_id" searchWhenChanged="false">
          <label>Network</label>
          <search>
            <query> index="someindex" | top ids </query>
            <earliest>@d</earliest>
            <latest>now</latest>
          </search>
          <choice value="*">All</choice>
          <change>
            <unset token="form.my_id_name_multiselect"></unset>
          </change>
          <default>*</default>
          <initialValue>*</initialValue>
        </input>
 <input type="multiselect" token="my_id_name_multiselect" searchWhenChanged="false">
      <label>Name</label>
      <choice value="*">All</choice>
      <search>
        <query>ndex="someindex" | where id=$my_id$ | table id_name</query>
        <earliest>@d</earliest>
        <latest>now</latest>
      </search>
      <default>*</default>
      <initialValue>*</initialValue>
      <prefix>(</prefix>
      <suffix>)</suffix>
      <valuePrefix>id_name="</valuePrefix>
      <valueSuffix>"</valueSuffix>
      <delimiter> OR </delimiter>
    </input>
</fieldset>
</form>

Hope this helps
