question about how to draw a complex graphic correctly or effectively?

[Willia-Yang]

I want create a graphic like in the picture by sirius, and the graphic need to meet the following characteristics:

1.header compartment

• ≪part≫: A static text non-editable
• part's name: Editable

2.attributes compartment

• attributes in italic, non-editable
• the list of attributes

3.actions compartment

• actions in italic, non-editable
• the list of actions

I have already drawn the shape of the graphic. the correspondence between the odesign file and the diagram is shown by arrows

as you can see the .odesign file uses several containers to implement the header compartment, and if i dont set all the style color same, the bug will appear,

I wonder if my implementation is correct or if there is a better way to implement it.
