Select in HTML the Elements to Hide in Generated PDF

EVO HTML to PDF Converter for .NET Documentation

EVO HTML to PDF Converter allows you select directly in HTML the elements to exclude from rendering to PDF by setting the data-exclude attribute on HTML elements you want to exclude. The converter does not reflow the HTML content when you exclude an element from rendering and the place where the element would be normally rendered remains blank. If you want to reflow the HTML content when the HTML element is hidden, you have to set display:none style for HTML element, eventually creating two separate stylesheets for screen and for print.
