How can i use more categories with Filterby and more columns? Do is use an Array?

Hello!

I checked your sp-bootstrap-list-viewer, it's a nice modern combination of SPServices with bootstrap. I am often using SPServices to grab list items from several lists in Site Collection.

Can you suggest how to combine multiple lists from different sites / sub-sites in this one view?
What I am missing from my current SPServices implementations - where to specify "webURL" / or several webURL's for the lists in your script?

I am often using an array for that - like:

var urls = [
{
name : "http://...subsite1"
},
{
name : "http://...subsite2"
},
...

for (var i = 0; i < urls.length; i++) {
$().SPServices({
operation: "GetListItems",
webURL: urls[i].name,
...

and it works quite good - for example with listing menu items.

Thank you in advance for any suggestions!

Best regards,
Marcin
