How to create drop-down list in Portal??

Question

My case: I have three locations A B C(in the database) for example.
I would like to use drop-down list to show list of All, A, B, and C.
After I choose any of them, for example A, it must show all the data of that particular location and if it is All it must show data of all three locations.
By using Simple Parameter, it's just a static one but I prefer the dynamic one that get directly from the database. And I also got a problem of showing all locations by choosing All in my dropdown menu
Any idea??!?
Thank you so much.

You could try a dynamic page:<br>
<br>
&LT;html&GT;<br>
&LT;body&GT;<br>
<br>
&LT;form action="http://host.port/pls/portal/etc." method="get"&GT;<br>
&LT;select name="location"&GT;<br>
&LT;ORACLE&GT;<br>
for rec in (select loc_code, loc_name from locations union select '-1' id, 'All' loc_name from dual)<br>
loop<br>
htp.p('&LT;option value="' || rec.loc_code || '"&GT;' || rec.loc_name || '&LT;/option&GT;');<br>
end loop;<br>
&LT;ORACLE&GT;<br>
&LT;/select&GT;<br>
&LT;/form&GT;<br>
<br>
&LT;/body&GT;<br>
&LT;/html&GT;<br>
<br>
The form should then call your page with a &location=loc_code in the url. Using a page parameter and a bound variable you can access that. You may need to use a decode in your sql to deal with the All scenario:<br>
<br>
select ..... where loc_code like decode(:location, -1, loc_code, :location)<br>
<br>
Hope this helps.<br>
