Currently, I had the need to build a list of checkboxes that were contained within a list box.
This gave the ability to have multiple selections in a list and the user could select multiple choices without having to hold down the Ctrl key.
Code
Basically you place your Standard Check Box field where ever you like and put this Pass-Thru HTML around it
<STYLE TYPE='text/css'>
.FIELDSET {height:80; width:240; border-top:solid thin
black; border-left:solid thin black; border-bottom:solid thin #D3D3D3;
border-right:solid thin #D3D3D3; overflow:auto}
</STYLE>
<FIELDSET CLASS="FIELDSET"> [PUT CHECKBOX FIELD HERE]
</FIELDSET>
You can change the style formatting to be as simple or as complex as you like.
e.g. "height:120; width:250; border:0;overflow:auto"
would give you a list with no border, nice and plain and simple.
