Add more dynamic select lookup and new record from the select

Add 2 or more controls for larger dependencies. Only 1 is the standard, but many times we can have 2 or more depending on the case. Example: country, department, province, sector, neighborhood.

Add a button, to add the new record of the select so as not to have to leave the form where it is being loaded.
Within the properties of the control, below the inputsearch, make a dynamic that can select the table to open as a popup to add the record belonging to the select.
I put with N or New the possible places where the new record button would be. In my opinion where it would be better is below the search.

I think these two requirements are useful.
