Possible to mix renderers and editors?

Question

Currently, I have an Accordion with a number of data grids
that contain different information. Items can be dragged from any
of the grids to a common grid outside the accordion, whereby the
drag/drop handler populates the target grid with appropriate data
that represents where it came from.
Here's what I need to do now:
This common grid contains a "quantity" column. Depending on
the type of data that was dropped into the grid, this value may or
may not be editable. When it is editable, it may be limited to a
upper limit that is determined from a data item that was dragged
with it, or it may not have an upper limit at all. I want to render
the current value as a normal number. For quantities that cannot be
edited, clicking on the value should not open it to edit (I have
that much). For values that have a defined limit, I want a numeric
stepper to appear with the defined limits. For values that have no
upper limit, I want a text input field to appear.
How do I approach this?

You'll have to make use of the itemEditBegin event and
manually create your item editor depending on the data. There's
some info here:
