Themelets are to Morph, what templates are to Joomla.
The concept of child themes
The concept of child themes was borrowed from the Wordpress theming community. The idea is that the parent theme (or in Joomla’s case, template) handles the majority of the grunt work, where the child theme hosts an individual users customizations that are specific to his or her site. By keeping those changes separate it allows the user to upgrade without having to worry that his or her changes will be lost in the process.
We applied this same methodology to Morph, as it gives us the freedom to continue developing, refining and innovating the core framework, without having to upgrade every single template with each update.
Being design concepts, themelets are generally only ever made up of css, javascript and images and are based on the idea that your sites content and design elements should always be kept separate from one another.
Installing themelets
Because themelets are a new concept to Joomla and unique to Morph, there are only two ways that you can install a themelet.
The first method is via our own custom installer, that you are presented with when installing Configurator and the second method is from within the Configurator, via the Tools > Universal Installer tab.
Customizing your themelet
Once you have installed your themelet, you can go to the customization tab in Configurator and configure your sites logo, colors, background settings and more.
Developing your own themelet
At present the easiest way to develop your own themelets is to use the light base as a starting point. Make a copy of the morph_assets/light-base folder, the rename the folder to your own themelet name and update the themelet information in the themeletDetails.xml file.
We will be releasing comprehensive tutorials on how to get started with themelet development once Morph is stable, but in the mean time you can see more detailed instructions here.
