Clarify overriding FlexForm in TCEFORM (#409)

- add section header in description on top of page, so we can link to it - add links to general description "Applying properties to FlexForm fields" - Use flexFieldNames with escaped dots in some examples - Use a real example in the general section - add description that dots in FlexForm fields must be escaped Resolves: #404 --------- Co-authored-by: Chris Müller <[email protected]>

+Applying properties to FlexForm fields
+--------------------------------------
+
+Other properties also apply to :ref:`FlexForm <t3coreapi:flexforms>` fields, in this case the full property
 path including the data structure key has to be set:
-`TCEFORM.[tableName].[fieldName].[dataStructureKey].[flexSheet].[flexFieldName].[propertyName]`.
+
+.. code-block:: typoscript
+
+    # TCEFORM.[tableName].[fieldName].[dataStructureKey].[flexSheet].[flexFieldName with escaped dots].[propertyName]
+    TCEFORM.tt_content.pi_flexform.sfregister_create.sDEF.settings\.fields\.selected.addItems.ZZZ = ZZZ
+
+The sheet name (sDEF) must be given only if the FlexForm has a sheet.
+
 The `[dataStructureKey]` represents the key of a FlexForm in
 :php:`$GLOBALS['TCA'][<tableName>]['columns'][<field>]['config']['ds']`. This key will be split into up to
 two parts. By default the first part will be used as identifier of the FlexForm in TSconfig. The second part
 will override the identifier if it is not empty, `list` or `*`. For example the identifier of the key
 `myext_pi1,list` will be `myext_pi1` and of the key `*,my_CType` it will be `my_CType`. See section
 :ref:`Pointing to a data structure <t3tca:columns-flex-ds-pointer>` of the TCA reference for details.
 
+The flexFieldName is the name of the property in the FlexForm. If it contains
+dots ('.'), these must be escaped with backslash.
+
 Some properties apply to whole FlexForm sheets, their property path is
 `TCEFORM.[tableName].[fieldName].[dataStructureKey].[flexSheet].[propertyName]`.
