A solution for advanced search for countries, state and city

I have found a little annoying bug in the advanced search widget when you are selecting different countries, states and city.

For example when you select a country like america there is a slight delay before the states are populated for the state field and sometimes you have to click the state field again for it to show. It gets even crazier when you have multiple countries, states and cities as when a you select different countries, sometimes the previous data for the state field such as US still shows up as states for UK.

I know the database takes a while to load data sometimes, but considering a user who does not care about that, I think it would be wise to put a feature in place where when the database is busy searching, there is some indication, such as a icon that tells the user that the data is being loaded.

Don’t believe try adding some different countries along with there state and cities and then load different countries, you will see the delay.

I know you will say if you wait a little it will load properly, but not all users will wait, so a little circle spinning saying please wait until the data is loaded can improve users experience
