New form column with only Wednesdays to select

[Tonje Waasjø]

My customer want's to have a field where you can only pick the Wednesdays in the future as dates. Is this possible? It don't have to be a datefield, as long as it has the dates in.

You should use two text columns and link then with formula together

Hi @Alireza Rahimifarid. Thanks for answering. Do you have an example? I have looked at this site https://support.office.com/en-gb/article/examples-of-common-formulas-in-sharepoint-lists-d81f5f21-2b... and some others, but doesn't see how I can use this to get only Wednesdays as "dates to choose from?
