Presto edits content using a so-called What-You-See-Is-What-You-Get (WYSIWYG) HTML editor.  The editor enables users in most cases to rise above the rigamarole of having to code HTML tags (e.g. <b>this is bolded</b>) directly.  It provides a user with a content editing area and menu options for managing font style, bulleting, tables, images and links.  The editor provides a "View Source" mode so users can delve into any technical HTML issues that the WYSIWYG editing mode is not able to manage.

By default, Presto comes with the open source editor called "FCKEditor" (http://fckeditor.net), named after its main developer, Frederico Caldeira Knabben.  It competes with its commercial counterparts in terms of features, and so usually our clients need nothing else.  It includes a MS Word clean option, a spellcheck option, custom stylesheets, browser compatibility, and XHTML validation. 

Presto has supported ActiveEdit 4.0 and soEditor 2.5 in the past, but we are no longer using these editors for technical and value reasons.

Generally WYSIWYG editors don't do enough to ensure text is correctly coded with style tags.  For example, text can be inside one style tag, and after applying another style, the tags for the new style are wrapped around the existing one - instead of replacing it - and so no change would have occured in display.  Sometimes you have to get into the nitty gritty and look at the HTML code to see what is happening.

The WYSIWYG editor is implemented as a module in Presto that can be literally "dropped-in" wherever HTML content needs to be edited in Presto forms.
