What whould you guys recommend?
I feel that there are too much frameworks in web world and am not sure which ones are good. I've researched a bit, tried Polymer but it doesn't feel mature enough. ExtJS is priced out of our league. Material UI is missing a tree widget and I have no idea how hard is it to implement drag and drop there.
So my current picks are dojo or wt. However may say dojo misses documentation, the architecture is old and it's hard to debug. Also any optionion on wt and other toolits would be highly appreciated.
