If you create a field in TemplaVoilà you have in the "Form" section a 
form field "Form configuration:". Here you can define how the field 
looks and how it behaves. This configuration is basically what is 
possible in TCA configuration, but written as XML.
For example for a "plain input field" the configuration is

<type>input</type>
<size>48</size>
<eval>trim</eval>

If you lookup the options for an input field in the TCA reference [1] 
you'll find the options for 'eval'. You could use

<eval>required,trim</eval>

to make the field required.


I think that you want something different? Maybe you want the editor to 
add extra copies of the same fields (or sets of fields). For example to 
create a list of links where the editor can determine how many links 
should be in the list.

This can be done in TemplaVoilà by using Section Containers and 
Containers For Elements [2]. The tutorial has screenshots of older 
versions of TYPO3 and TemplaVoilà but the functionality is still the same.
