Hi

A dropdown can only be linked to one variable and that variable can only have one value. It is not possible to have two defaults.  I recommend you use a aggregate from your preparation as the source list for the dropdown. Sort  and filter the aggregate so that the two values you prefer shows at the top of the list. You can use a numeric SortOrder attribute to sort the list.

Hope it helps. 

Hello Tamirys.

There is a way. The same way you send null to select all, you can set and send a custom value to select one or other.

Was I clear or should I send an example?

Do you mean you're using the Dropdown Select with a List Box?

Hi Tamirys,

On a traditional wep app, you'll need to use a ListBox widget, which does allow you to have multiple selected values, and lets you pre-select any of them, and then use either the DropDown Select control from the OutSystemsUIWeb library, of, if you're on an older platform version that doesn't have that, Chosen, from the Forge, to make it look nice.

Here it goes Tamirys.

Disclaimer:  I learned this in my PHP days and never thought in a OS specific way to do it :) 

I made an example that filters by day of week. it allows to group weekdays or weekends.

1. I created a struture to feed the dropdown (I could use the Special List section, but OS changes the ids of type text in the dropdown so I don't trust it).

The order by attribute is not relevant. I simply left some space between my special filters and the standard 1 to 7 from the static.

Then on the query I place special conditions.

Nothing fancy and can be expanded when needed.

Very helpful and detailed write-up
