Hey @susanu thanks for the PR.

AFAIK, this options are only used by filters that need them. If you pass a string to it, the filter is a "single value" filter, so why not use the simple filter instead?

I am just trying to figure out the use case for a string in these options. Can you provide me some example ?

Cheers

Please check https://backpackforlaravel.com/docs/6.x/crud-filters#select2_ajax-1
When you use select2_ajax filter the "values" is an url
