I suspect it's because there's a bit more complexity with nested transforms
and things like that....it should be possible, but I've not got any time
for a day or two...however, if you look at
http://svg.dabbles.info/snaptut-loadselect this has a bit more complex
calculations going on (so it takes care of transformed drags...the original
code you have in the fiddle drags at a different rate to the mouse
movement). If you paste
https://gist.githubusercontent.com/kevinG73/5b085dd74cec4e1a2fdfd93893373d9e/raw/6f994b7ebea13798a58d64222d7b9cfc634c93c2/puzzle.svg
over where it says "Bird.svg" near the bottom of the code (you can edit
that page live). You will see you can click and drag there and it looks
ok....
So I think it's a case of combining that code or similar, and then adding
similar collision detection like the other example. I may get a bit more
time at the weekend or next week if still stuck.
It "should" be possible though, but it is a bit fiddly and complex.

I do not understand what you mean ?
I can always drag and drop even on the code I sent you , it's just how to limit the drag and drop that i look for

The drag and drop on the original doesn't work correctly. If you drag it 100px, it only moves 50px (roughly).

Btw you can probably hack/fix it like the example, but you may find you have later issues with different setups, not sure. If you don't mind that, then you just need to add basic collision detection in your move handler.

Sorry, I haven't had chance to look at this, and may not for a while currently. The transform stuff I did back in those days may be overcomplicated stuff, I'm really not sure without a bit of time to sit down and check if it really should work for this case actually...I note this old (potentially buggier if nested transforms are used) but simpler plugin version feels better possibly... http://svg.dabbles.info/snaptut-drag-limit it feels like it just needs bounding check offset minus the starting position or something.
Sorry I haven't had any real time to check, I like this stuff, it's possible I may get a bit more time in the future, but I can't guarantee anything atm.
