Need help with adding a parameter to app_commands.choices

[mattskinners]

This is what my code looks like now. I want to add a parameter to the choice 'custom', so when user selects it another field pops up in which he can insert a date.
I want it to work like this: /calendar [user chooses option "Custom"] [another field pops out here for user to enter a date]
Visual representation:

I just can't figure it out. Any help is appreciated.

This is not possible with slash commands currently. Discord doesn't have inter-parameter dependency rules that allows you to activate fields / making them required because of a choice inside another option...

You could handle it in code that it will tell the user an error when "Custom" was chosen without a date and have date as an optional parameter but inside the UI what you want is not possible as a discord limitation
