Multi-line labeling

[YimanSong]

I want to be able to label in multiple lines instead of just one line. So the user would be able define the maximun number of characters can be shown in one line.

The Maplex extension contains a "stack label" placement feature as you've described.

Hi Yiman,

This is possible to do using the Maplex stacking option.  More information in the documentation here:
