For a content used in Joomla Article Manager, the only require field is the title, but you can save what you want in this title.

To insert a dynamic value use a text field:

Select "As Title Only" if you want create the content title only with this text field.

Select "As Title (Multi-Fields) & Text" if you want use this text field in your content title but in combination with other fields.

To insert a static string or a date like content creation date or content modification date use a hidden field:

To insert a static string in content tile select "Value as Title". In this case the default value of the hidden field is inserted in your content title.

To insert a date in content title use "Creation Date as Title" or "Modification Date As Title".

jSeblod CCK allow you to create a title with any text field or hidden field. So you can have a dynamic field (text field) selected in the form, or a static value (hidden field). But much better, you can create your title field with many field values.

For example :

• build a title like "My Restaurant : reserved by Mr John". You can consider the string "My Restaurant : reserved by " as a hidden field with this static string as default value and "John" as a text field which is fill by the person who reserved.
• build a title with the lastname and firstname of the user who submit the content. Insert in your content type 2 text fields one for the lastname and the other for firstname, select for both text fields the option "As Title (Multi-Fields) & Text"
