I’ve just installed Modx to have a look at it but there’s no WYSYWYG editor in the Resource Content field. Does this need to be installed separately? If I want to install a template set from someone else, is that installed via packet manager?
Yes, you have to install the WYSYWYG from package manager, it’s TinyMCE. If the template you want to install has been packaged as an extra then yes, you would install it using package management too. If it’s just a HTML/CSS template then you will need to port it into MODx which is a pretty painless process
