The cardinality is 1..1 and type of the attribute to which the UI element is binded must have fixed domain values. In the above screen I have binded the drop down by key UI element to the attribute of type BSTYP and the drop down UI element lists all the fixed domain values of the BSTYP. Note : With the drop down by key UI element we can only have only fixed domain values and if we need some more option we need to include it in the dictionary domain level only. If the drop down by Key UI element is binded to a cell editor of a table UI element the drop down can have only fixed values for all the row item where as the drop down list can be different for each row in drop down by index. Now let us see an simple example where I am going to set a drop down by key then read and display the value selected. Step 1 : Go to SE80 Tcode and create a webdynpro component.
