Add to a dynamic dropdown

[dbcase]

Hi,

I have this XML code

 <input type="dropdown" token="Product_token" searchWhenChanged="true">
      <label>Select a Product</label>
      <search>
      <query>index=wholesale_app  product|dedup product</query>
      <earliest>-1d</earliest>
        <latest>now</latest>
      </search>

      <fieldForLabel>product</fieldForLabel>
      <fieldForValue>product</fieldForValue>


    </input>

And it works just fine. I populates a dropdown with 2 values (lets call them Product 1 and Product 2) and I have working queries that adjust when the user selects one of the two products. So far so good. Now what I'd like to do is manually insert a "all" product so the users can select it and will see all the values regardless of product. Is there a way to manually insert a value to a dynamic dropdown?

There's probably a good way to do this with token manipulation, too, but I have an idea for how to append a small bit of SPL to the end of your query and slightly change the XML to reach your goal. If you add a field called "product_name" to each event and fill it with the current value of "product" and then append a dummy event with product_name="All" and product="*", and then modify your XML slightly to use the fieldForLabel of product_name, then you should be set. So all together, it looks like this:

 <input type="dropdown" token="Product_token" searchWhenChanged="true">
       <label>Select a Product</label>
       <search>
       <query>index=wholesale_app  product|dedup product | eval product_name=product | append [| stats count | eval product="*", product_name="All" | fields - count]</query>
       <earliest>-1d</earliest>
         <latest>now</latest>
       </search>
       <fieldForLabel>product_name</fieldForLabel>
       <fieldForValue>product</fieldForValue>
</input>

Hi!

Try this:

  <input type="dropdown" token="Product_token" searchWhenChanged="true">
       <label>Select a Product</label>
       <search>
       <query>index=wholesale_app  product|dedup product</query>
       <earliest>-1d</earliest>
         <latest>now</latest>
       </search>
       <fieldForLabel>product</fieldForLabel>
       <fieldForValue>product</fieldForValue>

       <choice value="*">- All -</choice>
      <default>*</default>
      <initialValue>*</initialValue>
     </input>

Tell me if it's ok for you 🙂
Regards!
