Only want to show up one day

[chochachimi]

Hi! 

ive been stuck since 3 days ago. I made an app with column type date, but I want the calendar to only have Thursdays, other days cannot be selected.

Thank you in advance!

AFIK you cannot control what days are shown in the date picker.

A few things you could do that I can think of

1. set the valid_if setting of the field to WEEKDAY([_THIS]) = 5 . 
2. in the suggested values, set a list of thursdays close to today (i.e.

   LIST(
    ...
    today() - (weekday(TODAY()) - 5) - 7,
    today() - (weekday(TODAY()) - 5),
    today() - (weekday(TODAY()) - 5) + 7
    ...
   )
   
   add as many as you want... 
   you can tweak it to show only future dates if that is what you need​
