Hi! I enjoyed searching, but English is not my own language for me .. Therefore, I did not find the solution of my easier question ..
I am a novice in WP and Metabox... I know a little PHP and OOP
The problem is:
1) There is a BMW heading (this is a BRAND taxonomy)
2) There is also X5 (taxonomy or Fields?? MODEL)
3) I would like to be able to choose a BRAND when filling out the news first ... and only then all MODELS of this brand appeared in the next field ...
4) And if you add a new model - it must contact the BMW brand ...
I'm a little confused how to organize it correctly (either through taxonomy rubrics, whether taxonomy tags)?
Could you give me an example (I suspect that you need to use Callback)?
