Ted,
I'm afraid that's not possible at the moment, unless you're willing to
override a sizable chunk of code in Exhibit, as below.
The code in question is in
http://static.simile.mit.edu/exhibit/api-2.1.0/scripts/ui/views/ordered-view-frame.js
Search for
Exhibit.OrderedViewFrame.prototype._internalReconstruct
Within that function, search for
var processNonNumericLevel = function(items, index, values, valueType) {
...
if (valueType == "item") {
...
} else { // text
...
}
You want another case
var processNonNumericLevel = function(items, index, values, valueType) {
...
if (valueType == "item") {
...
} else if (order.property == "type" && order.forward) {
var map = {
"US Legal Databases" : 0,
"Foreign Law Databases" : 1,
... add everything here ...
};
values.visit(function(typeID) {
keys.push({ display: typeID, index: typeID in map ?
map[typeID] : -1 });
});
compareKeys = function(key1, key2) {
var c = key1.index - key2.index;
return c != 0 ? c :
key1.display.localeCompare(key2.display);
};
retrieveItems = function(key) {
return database.getSubjects(key.display, "type", null,
items);
};
} else { // text
...
}
So you would need to copy the whole
Exhibit.OrderedViewFrame.prototype._internalReconstruct function and add
it after including exhibit-api.js, with the changes shown above:
<script src=" .... /exhibit-api.js"></script>
<script>
Exhibit.OrderedViewFrame.prototype._internalReconstruct =
function() {
... copied and pasted code, with changes ...
};
</script>
