1. Algolia
If you want to add forms on your website with autocomplete features, this is the library that you should use. It is accurate and fast. We specifically loved the map feature which allows you to add a map in the address field for searching locations.
2. Wired Elements
Let’s suppose someone asked you to create a page where the elements seem to be hand drawn. To be clear, there should not be any pattern between 2 elements. Wired Elements is the solution to that. This JavaScript \ library enables you to design UI elements and make them look like they have been drawn by hand.
