I've written a basic map app with Dojo and Openlayers (using titlebar , toggle buttons , checkbox tree and some more). I've seen ArcGIS JS Api has nice tooltip / balloon and GeoExt has nice Legend Panel which I want to add both to my app.
ArcGIS looked a little bit complicated to add (it interrupted Dojo) so I passed it. Can I add only GeoExt just for the legend Panel or will I need to choose either GeoExt or Dojo in my app ?
