Hello,

Please read this introduction and the check the question

introduction :
In the Activities Module under Contacts, we can see many buttons such as:
  1. Create Task
  2. Schedule a meeting
  3. Schedule Call
  4. Compose mail


Code wise, Activities Module looks very different from other modules!

On the other hand other modules do not have more then 2 buttons:
  1. Create
  2. Select


If we go to ./include/generic/SugarWidgets
we find Subpanel buttons

Questions:
  1. How could we create our own Buttons?
  2. How could we add more buttons to already existing Subpanels while using the Module Installer?
