You could mean one of 3 things, either a <SELECT> box which is a drop
down list, or radio buttons or checkboxes.

It depends what form element you mean.
<SELECT> actually returns only the selection that is "selected".
with:
<SELECT name="freds-status">
<OPTION VALUE="sacked">
<OPTION VALUE="about to be sacked">
<OPTION VALUE="earning">
<OPTION VALUE="raking it in" SELECTED>
<OPTION VALUE="java servlet programmer">
</SELECT>
the servlet bit:
String status=request,getParameter("freds-status");
will make status=="raking it in"
Whereas <input type="checkbox"> can be used to get many different
values, like this:
<form ...>
<input type="checkbox" name="freds-abilities" value="java
servlets">Java Servlets
<input type="checkbox" name="freds-abilities" value="network
management">Nets
<input type="checkbox" name="freds-abilities" value="microtoss
tools">M$
</form>
If the user selects "java servlets" and "network management" then the
code:
String[] abilities=request.getParameterValues("freds-abilities");
will get the following array:
{ "java servlets" "network management" }
Radio buttons are similar to SELECT boxes.
Stuff like this is a bit off-topic because you can always find it out
from a good HTML book.
