You already know that in HTML there is no search option in the dropdown element. When you press any single key on the dropdown then it takes you to the option but not allows you to search whole or particular string.
There are many jQuery plugins which do this for you.
But in this tutorial, I am not using any jQuery plugins for implementing it.
When it’s required?
This kind of feature generally requires when we have the long list of options in the Select element and want to make an easier navigation for users.
By this way, you enable user to search option on dropdown
The most common example is Country Dropdown which you have seen on many websites when you go for Registration.
What in the Demonstration ?
Creating a simple form which also contains a drop-down element. When the dropdown gets clicked then showing the Search Box and according to the input show suggestion.
