# Option: valid_elements

This option should contain a comma separated list element convertion chunks. Each chunk contains information about how one element and it's attributes should be treated. The default rule set for this option is specified below.

Control characters:
, | Separates element chunk definitions.
/ | Separates element synonymous. The first element is the one that will be outputted.
| | Separates attribute definitions.
[ | Starts a new attribute list for a element definition.
] | Ends a attribute list for a element definition.
= | Makes the attribute to default to the specified value. For example "target=_blank"
: | Makes the attribute to be forced to the specified value. For example "border:0"
< | Verifies the value of a attribute. For example "target<_blank?_self"
? | Separates attribute verification values, see above.
+ | Makes the element open if no child nodes exists. Example: +a.
- | Enables removal of empty elements such as >strong /<. Example: -strong.
# | Enables padding of empty elements, this will padd with &nbsp; if they are empty. Example: #p.

Wildcards such as *,+,? may be used in element or attribute name matching.

Special variables:
{$uid} Results in a unique ID. For example "p[id:{$uid}]".
Use *[*] to include all elements and all attributes this can be very useful when used with the invalid_elements option.

### Example of usage of the valid_elements option:

This example string tells TinyMCE to remove all elements that are not a "a, strong, div or br" element, convert b elements to strong elements, default target to "_blank" and keep the href, target and align attributes of the elements.

    tinyMCE.init({
    	...
    	valid_elements : "a[href|target=_blank],strong/b,div[align],br"
    });

### Default rule set:

This is the default string used by TinyMCE to cleanup the HTML contents.
