I have developed a custom webhook which shows a drop down using the splunk-search-dropdown.
<splunk-search-dropdown name="action.msgbus.param.alertGroup"search="| inputlookup alert_group_lookup.csv "label-field="ALERT_GROUP" value-field="ALERT_GROUP"/>
This populates the lookup in dropdown but does not allow me to write something in the drop down text box.
Since my dropdown will have 10,000 values, I need the ability to search the drop down.
Please help, what I need to change
