Is it possible, and what would be the approach, to create an
apex:commandButton which displays a dropdown when clicked, in the same fashion as the Manage Members button on the Campaign object:
To clarify the dropdown list I would list to be dynamic. I've just been looking at this approach, and it works BUT I need the drop down/apex:commandLinks to be dynamically generated: http://www.tehnrd.com/custom-multi-select-buttons/
I want to add a button to a custom product entry screen which will add a group of Products as OpportunityLineItems, however the Products are categorised by year and the choice will be one of the years or all of them (not a mixture of years).
Just found an idea for it: https://success.salesforce.com/ideaview?id=08730000000BqRhAAK
