All Loadable controls are in their own namespaces and must be prefixed with their namespace. In addition to the built in loadables, you can create your own loadable libraries for use with IntraWeb.
Load on Demand
Loadables are loaded on demand and will not be loaded if controls controls are not used. If the IntraWebMega distribution or other merged library is used, the IntraWeb code for the controls will be preloaded but the libraries that are used such as JQuery, Bootstrap, etc will not be loaded until the first control that belongs to them is loaded. This saves bandwidth and time by only loading support libraries that are needed.
