Documentation request: change the UI for position configuration

[ivanjaros]

The position configuration for tooltip, menu... elements is hard to use. I've been using Quasar for years, yet it always takes me a long time to configure the correct result.

I suggest the documentation page to replace its current ui

with simpler version for both elements

where user can just click on the point for the parent and for the child which he wants to connect and that's it
