This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Custom content elements¶
Most projects need custom content elements besides the ones available from the core. These could be a list of links, an image slider, an element for an introduction text, etcetera. The core already provides enough functionality for this. Compared to the possibilities supplied by TemplaVoilà the only thing missing is an area inside a content element where an editor can put other content elements. In many cases this can be solved for a design by supplying extra page templates, but if this functionality is needed the extension “gridelements” can provide it.
