Custom data source without options - Sprout Forms Is it possible to create a custom data source that does not include end user options? I have tried not including the getOptionsHtml(), returning null, returning an empty string, and just return and the all fail.
A Custom Data Source does not require any settings. If desired, you could create a Data Source that only had a title and did whatever logic and queries that you wanted behind the scenes.

In Craft 2, getOptionsHtml returns null by default and shouldn't need to be set to anything in your Custom Data Source if that is desired:

public function getOptionsHtml()
{
    return null;
}


In Craft 3, the default is to not display any settings also:

public function getSettingsHtml()
{
    return null;
}
