Hybrid drop-down menu / image-map menus
Drill-down
iMMap Express and iMMap Pro can accept single index files of
up to about 1000 entries in size. It is unlikely that you
will want more than this for an imagemap.
However if you want to make your imagemap handle a seriously
large and complex navigation system, you can use the DRILL
feature present in the Express and Pro variants of our other
applet ranges. The DRILL feature is effectively a runtime
replacement of the current index file by a new index file.
It can be used to enable applets to handle infinitely sized
indices (and to break these indices down into smaller files
which can be loaded faster across the network).
In the iMMap applet, the DRILL feature can be used to dynamically
change the MAP file and the image itself as well. This means that
if iMMap, for example, is in a side frame on your website, you can
load page-sensitive images, maps and indices into the applet without
actually reloading the applet.
Due to these additional features, the DRILL command has a slightly
different syntax in iMMap.
"TEXT:My Text" "1" "" "LINK:myPage1.html,myFrame;
DRILL:myNewMap.txt,myNewImage.gif,myNewIndex.txt" "[message]"
In the other applets, DRILL is just followed by a single file name
(the name of the new index file). In iMMap, it must be followed by
three filenames - first the new MAP file, then the new image file,
and finally the new index file. In theory, any of these files could
be the same as the files already loaded into the applet, but they must
be named again.
