Integrate plain HTML search form and override WordPress get_search_form function.
Let me show how to create a form with plain HTML and then override the existing WordPress get_search_form() function and give you a couple of ideas on autocomplete.
Now that we have a sample of our plain HTML search form let me show you how to integrate it and override the WordPress function that is responsible to generate and output a search form.
Now it comes to the tricky part how-to load the datalist options with terms from your database post and page content.
If it were up to me, I would combine options #1 and #2 to generate the datalist options. If you want to know how to do that, please comment below, and if I get more than several requests, I will write a second post of this tutorial where I will show you how to add an autocomplete functionality to your plain HTML search form.
‘Til the next one.
