We've got a situation where we want users to select a value from Drop-Down List 1 and have that value used as the 'default' (or what is initially provided in the window) of Drop-Down List 2. We do _not_ want the value of Drop-Down List 1 to filter Drop-Down List 2 so that is is filtered to only show what was passed from Drop-Down List 1 (from either a parameter or interaction).
Is there a way to have Drop-Down Lists default to a specific value while still retaining all the possible options of the list?
I found an answear to a similar question in this paper : "Mastering Parameters in SAS® Visual Analytics" at section "Adding Dynamic maximum functionality to drop-down list".
I just tried it and it worked for me.
The idea is to create a binary variable in your table that will flag your desired default value. Then add a filter logic on each SAS VA object that you want to filter to only takes rows that are flagged if the parameter is set to missing (i.e. if no value is selected in the dropdown list).
