-Topics allow for flexible free format data, sometimes you want to ensure strucutre to some of the topic information, this can be done with Forms e.g. saying what type of topic it is (e.g. Bug, Feature, FAQ entry etc) and then filling in fields using dropdowns, radio buttons etc.

-If forms are enabled for a Web and a topic has a form you will see it as a table when viewing the page. When you edit you will see the various edit controls below the normal text area. There will be a button at the top of the form marked _Change_ which allows you to change to a different form, or remove the form. If you edit a topic without a form, there will be a button _Add Form_, that let's you associate a form with the topic; note that changes you have made to the topic are not lost when you select this option.
+Include form-based input in topics, with unlimited, user-selectable forms per web; values stored as Meta Data
-You can search for topics with specific form data using the %SEARCH% variable - see [[TWikiVariables|Main/TWikiDocumentation#TWikiVariables]].

+By adding form-based input to free-form content, you can structure topics with unlimited, easily searchable categories. When forms are enabled for a web and selected in a topic, the form appears in edit mode, and the contents are rendered as a table when viewing the actual page. When editing, can switch forms, if more than one is defined, or remove forms entirely. Form input values are stored as [[TWikiMetaData|Main/TWikiDocumentation#TWiki_Meta_Data]]; all data is saved.
-Form Templates more powerful, flexible replacement for the original TWikiCategoryTable.
+Form Templates replace TWikiCategory Tables from the previous version of TWiki.

+## <a name="Form Template Elements"></a> Form Template Elements
-Main changes from TWikiCategoryTable: The templates for category view/edit have been dropped, and the forma renders to HTML on viewing.

-#### <a name="Migrating Existing Category Tabl"></a> Migrating Existing Category Table Data
-
-The new Form Template system should work with old Category Table data with no special conversion. Old data should be transparently upgraded to the new Meta format when a page imported from the old TWiki is edited and saved in the new system for the first time.
-
-On upgrading, the administrator must produce a form template topic for each web that uses the old Category Tables. `twikicatitems.tmpl` defines the categories and is used in the conversion. The form template must be set as the first item in the [[WebPreferences]] variable `=WEBFORM`. If it's not present, `view` works, but `edit` results in an _oops_ dialog result. If things aren't working correctly, there may be entries in `data/warning.txt`.

-- <code>[[...|/WebHome]]</code> can be used for force a link, at present <code>[[...|/WebHome]]</code> format is not supported
-- The "Tooltip message:" column is used as a tool tip for the field name (only if field name is a [[WikiName]]) - you only see the tooltip on edit
-- The first item in the list is the default item. Alternative initial values can be given in a topic template such as <code>**WebTopicEditTemplate**</code> or using fieldFLD=value or for checkboxes fieldFLDcheckbox=1 in URL
-- The topic definition is not read when a topic is viewed
