Using a select type input
Since this input creates a drop-down list, it works only with a limited number of possible values. To populate the list with values, click the input title bar and enter the values in the Aggregation Task field by clicking Edit. You can populate the Select input list in a couple of ways:
By entering a fixed list of values. Below you can see the syntax you must use to populate the list with different values:
["a", "b", "c", "d"]
Using a query. Below you can see how the query used in the Aggregation Task field of the input retrieves the values in the statusCode column.
query( from demo.ecommerce.data group by statusCode)
By default, you can only switch between the different values you have entered. To deselect a value and return to a neutral state, simply click on the drop-down list and hit the Esc key.
|Placeholder||Enter a placeholder text to show in the drop-down box by default.|
|Allow multiple options||Toggle on to have more than one option available to choose at the same time (value_1 OR value_2, and so on).|
|Menu always open||Toggle this on to keep the menu options always visible.|
|Disabled||Toggle on to block the input.|
Toggle off to disable the auto-completing option when entering characters in the drop-down box.
