Reusable Content

Form and gallery assets are permanently locked to site, because of their database and image capabilities respectively.

Yes and no. An asset chooser can be used as a form field for a component, but assets cannot be inserted into the component source code.

No.

Can I put a component or an asset inside a snippet?

Once a snippet is placed on a page, you can enter any kind of reusable content inside the snippet. However, depending on the snippet design, this may lead to unexpected results.

I placed my asset/component/snippet on a page, and now the page has a rendering error.

Any code inserted into a page, such as source code assets or the source code of a component or snippet, must either be XML-compliant or appropriately encoded, as it will be processed with the page XML before page publish.

Some common errors are:

1. All tags need to be closed.
   Unlike HTML, all tags in XML must close, either as self-closing tags or full tags.
   • <img /> or <img></img>
   • <br />
   • <hr />
   • <link /> or <link></link>
2. Boolean attributes must have a value.
   HTML has some attributes which are considered boolean, meaning the attribute can be listed without a value. XML requires all attributes to have associated values, so add a value repeating the name of the attribute.
   
   • async="async"
   • hidden="hidden"
3. Special characters must be encoded.
   XML treats certain special characters in a unique manner. Any instances of those characters which appear in page content need to be encoded appropriately.
