TextExt is a jQuery plugin that adds functionality like tags, auto-complete, placeholder text and filters to any standard HTML text input fields including text areas.
When a user starts typing in to the text field, a dropdown would be presented with possible suggestions to complete the input quicker. Similarly, if you enable Focus, it adds visual effect whenever user sets focus into the text area.
Prompts are similar to the placeholder text property of HTML5. It displays a visual user prompt in the text input area that is hidden as soon as the user focuses on the input field. The prompt is only show when the input field is blank or has no value.
