Set default selection for Gallery

[Titiwai]

I have a gallery display a list of dates.

Is there any formula could make the default selection of gallery to be today's date?

Yes - But, it Totally depends on the Items you are using.

Simple example :

Gallery Items :  [DateValue("2/1/2019"),DateValue("2/16/2019"),DateValue("2/28/2019"),DateValue("3/4/2019")]
Gallery Default : {Value: DateValue("2/28/2019")}  
OR
Gallery Default : {Value:Today()}  
Either of the above defaults work.

You have to observe the structure of the Items when specifying a Default value.  In the above example, no specific field name is given for each record/item, so value is assigned - and thus, the Default must follow with a record that specifies the Value.

This is EASILY overlooked, but MUST be observed.

So, Depending on the Items you have, you must observe as well the Default.  

Also, take a look at this recent post that discusses the very same issue of selecting defaults based on DataSource items. It is about URL Parameters, but it is also about selecting Defaults and the things you need to observe.

Hope this helps some.
