Hi,
There is a widget dropdown in RWA for which you just have to drag and drop that on your required screen. Then you have to enter following properties for that:
1. variable- in which it can store your selected value.
2. List: from which your data will come.
3. Option text: This property decides what to show at user end(particular attribute which we want to display)
4. Option Value: depends upon the requirement. Like if you want to store same attribute at backend then that will be selected and if Id only you want to store then Id attribute will be selected.
I hope this will solve your problem.
Best Regards
