Improve date format selection UI

[aaronrothschild]

Currently, the user needs to type in a date format to be used - manually. This introduces errors and confusion for the end-user. It would be better if we just gave them 8 choices in a list and didn't have to type anything in.

• (***) Improve the UI to use a radio or dropdown for the user to select their desired date format from a few options rather
• Add validation that the hashtag before the date is a minimum of 3 characters to ensure meeting items create valid hashtags

Yes, the current format is really painful and contributes to a bad UX.
Do we have any design for the proposed change?

Is this issue the same as #17? @hanzei

[hanzei]

As far as I understand #17 it's about validating the time format before saving it. That seems to be easier to accomplish then this ticket. Hence, I'm inclined to keep both open.

Discussion with some context about this issue: https://community.mattermost.com/core/pl/97x3akmh8jdc5mdg4afyedbhmr

Let's add these options:

"Month-day" (ie: Dec-4)
"day-Month" (ie: 4-Dec)
"month-day" (ie: 12-4 )
"day-month" (ie: 4-12 )
"year-month-day" (ie: 2020-12-4)

We will need a second field called "hashtag prefix" which the user can specify the "text" part of the hastag (such as "incident-room" or "TeamA") which is then concatenated with the date format they've chosen from the dropdown.

They would be rendered as:
"#TeamA-12-4" (assuming they chose the "month-day" option)

Somrthing like this:

Got it, thanks!
