placeholder for empty server response not working

[Commifreak]

Prerequisites

• [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x] The issue still exists against the latest master branch of yii2-widget-depdrop.
• [x] This is not an usage question. I confirm having gone through and read the documentation for ActiveForm and ActiveField.
• [x] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [x] I have attempted to find the simplest possible steps to reproduce the issue.
• [ ] I have included a failing test as a pull request (Optional).

Expected behavior and actual behavior

I set up SepDrop like the docs say - but this part is confusing: (https://demos.krajee.com/widget-details/depdrop#settings)

placeholder: string whether the dependent select has a default placeholder (with an empty value), when no records are found. You can set this to a label which will be displayed as an empty value. For optgroups this will be a disabled option. If you set this to null or empty string , it will not be displayed. Defaults to Select ....

placeholder: string the message to display when the ajax response returned from the server is null or an empty array. Defaults to No data found.

The settings key is double documented. When I leave it empty, the promised No data found is not displayed, when the server returns no result.

So:

• How to set default placeholder?
• How to set placeholder when DepDrop disables a field due to empty server response?
