This section provides information about XEO Web Components (XWC the visual layer of the XEO Framework. You'll find information about the components provided by XEO, you'll also find tutorials and reference material about how to create your own component or how to create a plugin to an existing component.You can find the following content in this section:

---++ XEO Web Components List <a name="webcomponents"></a>

The XEO Framework includes a set of pre-defined components to accelerate the programer's job. There are two types of components, the ones that can be used freely and the ones that are binded to XEO objects.

The components binded to XEO Models are designated *XEO Components* and the not-binded are *XVW Components* (there are XVW components which can be binded to XEO Models, but it's not a requirement).
---++++ XEO Components:

As explained before, XEO Components are typically binded to a XEO Object and there are several categories of components
