How to set field attributes type such as enumeration / boolean / text in Search UIBB when creating search creatria dynamically using default_config?

Hi Experts !

I am trying to build search UIBB where I need to configure the search criteria dynamically in the IF_FPM_GUIBB_SEARCH~GET_DEFAULT_CONFIG method.

Please can anyone tell me is it possible to set the attribute types in dynamic configuration .... because I need to create a drop down field in the selection screen.

Thanks !
