can anyone help to find a module or api which can diplay content dynamically?
"Display content dynamically" is very vague. Can you give more details about exactly what you are trying to do?
Thanks for your interest. i wanna know If I want a dropdown to be populated from a webservice output , how can I do it.
Without any more details about exactly what you want to do, all I can say is: you read from the webservice call, and and use PHP to generate the dropdown.
