I have a list of 30 items. In the screen I can see up to 10 items, then I have to click "2" tab on pagination to look for the next 10 items (Local variable: MaxRecords: 10). Instead of pagination I want use a button named "Show all". When I will click on that I want to see all the 30 items, then if I click again the list it will collapse and will show the first 10 items. How to achieve that? I am not talking about accordion. Is there any other way. Suggestion with a sample .oml file will be really helpful.
