#VarMETA
---+++ META -- displays meta-data
   * Provided mainly for use in templates, this variable generates the parts of the topic view that relate to meta-data (attachments, forms etc.) The =formfield= item is the most likely to be useful to casual users.
   * Syntax: =%<nop>META{ "item" ...}%=
   * Parameters:
     | *Item* | *Options* | *Description* |
     | ="formfield"= | =name="..."=: name of the field. The field value can be shortened as described in %SYSTEMWEB%.FormattedSearch for =$formfield=. %BR% \
                       =newline="..."=: by default, each newline character will be rewritten to =&lt;br /&gt;= to allow metadata that contains newlines to be used in tables, etc. =$n= indicates a newline character.%BR% \
                       =bar="..."=: by default, each vertical bar is rewritten to an HTML entity so as to not be mistaken for a table separator.%BR% \
                       =topic="..."=: Get meta info of "Topic" or "Web.Topic"; default ="%<nop>BASEWEB%.%<nop>BASETOPIC%"=. \

     | ="attachments"= | =all="on"= to show hidden attachments.%BR% \
                         =title="..."= to show a title - only if attachments are displayed.%BR% \
                         =template="..."= to use a custom template for the rendering of attachments; default =attachtables= is used.%BR% \

                    =prefix="..."=: Prefix that goes before parents, but only if there are parents, default =""=. %BR% \
                    =format="..."=: Format string used to display each parent topic where =$web= expands to the web name, and =$topic= expands to the topic name; default: ="[<nop>[$web.$topic][$topic]]"= %BR% \
                    =suffix="..."=: Suffix, only appears if there are parents; default =""=. %BR% \

                  | Generates the parent link |
   * __Attention:__ The base topic, not the current topic, is used if =%<nop>META{}%= is placed in an included topic. Add a =topic="%<nop>WEB%.%<nop>TOPIC%"= parameter if you need meta info of the current topic.
   * __Note:__ [[FormatTokens][Formatting tokens]] can be used for =newline=, =prefix=, =format=, =suffix= and =separator= options, such as =separator="$n   * "=
