There are six input options for you to choose from to tailor your required data collection method.
- Single-Line Text Box - This is a textbox that allows the user to enter a response.
- Multiple-Line Text Box - This is also a textbox (textarea), except it consists of multiple lines,
- Single-Selection Radio Buttons - This option offers the user a choice of multiple answers, allowing them to make one selection.
- Single-Selection Menu - This option also offers the user a choice of multiple answers except that it is presented as a dropdown menu. It also allows the user to make one selection.
- Multiple-Selection Menu - This option offers multiple choices to the user, allowing multiple selections to be made. This is presented as a drop down menu plus a selection box.
- Multiple-Selection Checkbox - This option also offers multiple choices to the user, allowing multiple selections to be made. This is presented as checkboxes.

For example say I added a new custom profile field for Real names, lets say that this is the 10th custom profile field on my board.
If I wanted to show this in the postbit I could add this to that template:
<if condition"$post['field10']">
Real name: $post[field10]<br />
<else />
<br />
</if>
What that basicly dose if check to see if the user entered anything into field 10, if so it will display this information, if not it will just insert a <br />.
If you need more information on using condition's like this, check out the support forums (www.vbulletin.com/forum) or the offical vBulletin template resource (www.vbulletin.org)
