# Field Types

### Title

This is the most important field type because it is used for designation of contest entries in the component and related extensions (modules and plugins).

{% hint style="warning" %}
It is not possible to create a contest without this field.
{% endhint %}

The value of this field will be used as alias in the URL and as the main visual entry identification: in the heading of entry page, in the page title, as a photo caption in the component and modules, in the list of search items and so on. In fact its behavior is quite similar to the 'Title' field of the core Joomla components.

For example, if you have a model agency contest, and it is better to use a participant fullname for this field. If it is a pet’s contest, then for this field you would use a pet name.

### Text

General text field.

### Textarea

Textarea field type is used for several lines of text entry.

### Calendar

Calendar field type is used for date time entry.

### Checkbox

Checkbox field type allows to select several values.

### Radio

Radio buttons are normally presented in radio groups. Only one radio button in a group can be selected at the same time.

### List

List field type allows to select only one value form the drop-down list.

### URL

URL field type is used for displaying a link to specified URL.

Custom fields in NorrCompetition are not the content types, as it commonly used in most CCK. NorrCompetition is not a CCK component and that is why the implementation of custom fields is quite simple.
