Many of the times there is need or requirement to insert raw HTML in a Joomla article or module. For example, embedding Google maps etc.
Unfortunately, sometimes the editor screen you are using will strip out the HTML code, or cause an error. Rather than having to turn the editor on/off in global configuration, there is an easier way.
Try this trick.
Make a super administrator, say “htmlinsert”. and then find him in the user manager and change his editor to “No Editor”.
Any time you need to work in raw html, log in with the user “htmlinsert” , front end or back end.
This also works for articles too.
