Problem:
You create a form for users in your page. When a user starts to fill the form, by default, browser shows options or some suggestions to fill in the field, based on earlier typed values. You need to disable this.
Solution:
Add the following code in the opening form tag.
The code:
<form autocomplete="off">
Explanation:
When the attribute “autocomplete” sets to “off”, it forbids the browser to display options.
