This is a feature that everyone has been asking for and I’ve finally got around to implementing it. You can now add an HTML WYSIWYG editor to the new ad submission description field. So if you’ve enabled the “Allow HTML Code” option in CP, your customers will be able to do some basic html markup to their ad submission!
This feature will be in v2.9.3 but if you wanted to get a head start and use it now, you can easily add it to your site. Use at your own risk though. This code worked fine for me but your configuration might be different.
