Is it possible to make a field from migx in extjs?
Not sure, what your question is.
I want to modify one plugin. Add one field to it and connect the migx configuration there.
I think that’s not that easy. Maybe easier to rebuild the whole with MIGXdb.
May I ask, which plugin?

you could easily recreate the CMP for the table in question with a MIGXdb CMP and add your MIGX field there
