Display a 'modal popup' anywhere in the system

Hello everyone this is my first post.
I am new to CodeIgniter and I have a question.
I was wondering if there is a way for me to load a div (modal popup) in any view of my project.
For example, I am performing a client registration and suddenly remembered a task I have to do next. Click on the menu above New Task and will open a popup and close it can keep customer records. The idea is that it is possible to anywhere in the system.
Is this possible?
