How to create a dynamic selection of sources in a dashboard?

[Urias]

I have multiple sources with information for an event. I want to make a Dashboard with a total overview of all info available on a given event, but be able to select which sources are displayed. As there are many sources and not all of them always contain event data, I want a dynamic list of check boxes to get a best possible workflow.

I've attempted with a "Multiselect" field dynamically populated with ... | stats values(sourcetype) as types | mvexpand types, but the resulting UI is quite hard to use. I see the ideal solution as a dynamic list of sources with info on the event where the user can select or deselect sources individually.

Is this possible, and how can I achieve this?

Here is an example to load Top 5 sourcetypes. Default and static choice value All may not be required. I have just added as example.

<form>
  <label>Example Dashboard with Sourcetype Check Boxes</label>
  <fieldset submitButton="false">
    <input type="time" token="selTime" searchWhenChanged="true">
      <label>Select Time</label>
      <default>
        <earliest>-60m@m</earliest>
        <latest>now</latest>
      </default>
    </input>
    <input type="checkbox" token="chkSourceType" searchWhenChanged="true">
      <label>Source Types</label>
      <choice value="*">All</choice>
      <prefix>sourcetype=</prefix>
      <valuePrefix>"</valuePrefix>
      <valueSuffix>"</valueSuffix>
      <delimiter> OR </delimiter>
      <fieldForLabel>sourcetype</fieldForLabel>
      <fieldForValue>sourcetype</fieldForValue>
      <search>
        <query>index=_internal earliest=$selTime.earliest$ latest=$selTime.latest$ |top 5 sourcetype | fields sourcetype</query>
      </search>
      <default>*</default>
    </input>
  </fieldset>
  <row>
    <panel>
      <chart>
        <search>
          <query>index=_internal status=* $chkSourceType$ | stats count by status</query>
          <earliest>$selTime.earliest$</earliest>
          <latest>$selTime.latest$</latest>
        </search>
        <option name="charting.chart">line</option>
      </chart>
    </panel>
  </row>
</form>

Thanks. Was looking for that part in check box input. Works with minor tweaking.
