Add feature dynamic display of the blocks or Fields

[AndreaGelmini]

Good morning.
I am very happy with this component . It is facilitating much customization crm my company

It solved many problems .

I wanted to ask how I can add a function that creates a dependency between a filed pick list and display modules .
l
I read around the web that you have to place a file in the folder of the module . I wanted to know if this can be done directly with module design
