On the attached app wanting to utlise the actions so when you click it eliminates certain options. Essentially a lisy box would do the trick but prefer it in this method if posible.
On the attached app refer to to the Downsizing box in blue on 1st tab.Trying to add an action to this so when you click it it exludes upsizing and only shows Downsizing properties.
Upsizing and Downsizing are identifed in the 'List field' (also identified on the list box to the right).
I don't see the box you are saying, but I can help you. If you have a field with values "Upsizing" and "Downsizing", then you can create a button, go to Actions and add "Select in Field" and add "Upsizing" or "Downsizing" depending what you want.
Clear me if i have understand your question right,
In your application you want to display when user select the Blue text object, the Downsizing data will display from List Field into Available properties text object.
