How to implement address autocomplete?

Use a web service that provides an address search. Then call this service in the saveInto of you address input fields. Then display the search results to the user.

Do you have any more specific questions?

Hi, If the data is from the database then for that you would have to create a custom picker for that. Let me know if this use case works for you then we can further help on it.

The service part is done. But which component will be used to display the suggestion of addresses to the user in the interface?

You can use any Appian interface component to do that. Depending on your use case, a simple grid or a list of card layouts for a more custom look.

I was hoping for something like search bar. Is this possible in interface?

I think a custom picker might be an option.

The separate suggest function calls that service and transforms the returned data into a datasubset.

We are using google places service for locations. So is there any way to generate address suggestion & search bar?

Hello Anik Dutta ,

You can create your integration using the Google maps connected system and operation type as Autocomplete for address and place names. call this in an expression rule and try to create a picker field. 

A custom picker is the only option you are left with to achieve this functionality it will automatically do the search thing also so no need of the search bar here.
Hope this helps!!
