F4 Help for offline interactive form

Hi all,

I'm creating an offline interactive form without webdynpro . There is one request to use f4 help for fields in one column of table.

I try to use drop-down list with dynamic binding with table in context. Everything works ok except one detail. The drop down-list always shows only one text value define in dynamic properties. Is it possible to force drop-down list to shows one text in normal state and different texts when users click on the list?

One example with country code: User will click on drop-down list, from the list with the names of countries he will select text 'Czech Republic', then the list will disappear and user will see in drop-down list like selected value only country code 'CS'. Is it possible?

Thank you for any advice
