Select with extra functional buttons

[yangsystem]

I want to add next to the select field an add button. the button should have programable functionality ( in my case I want an add new option modal for an model)

Also I want if it is possible if I have a form opened in a modal that has the select with the extra button/buttons to be able to open the second modal on top save the record and close only the second modal and refresh the records without closing the first modal
