Action Bar customization

Hi,

I am trying to customize the action bar. I need to add a new button. Following the instruction provided in the subform Custom_JS_Lite, I am able to add the menu items and they are working as intended. However the previously existing menu items are getting disturbed. I am not able to view the sub menu items.

Could someone tell me how to customize the action bar?

Thanks in advance,

When you say that the existing menu items are getting disturbed, what do you mean exactly? They are not displayed? Can you give some more detail? Maybe post some example code?
