• I agree to follow the Code of Conduct.
• I have searched for existing issues that already include this feature request, without success.

Describe the Feature Request

I would like to add something to closed task: #24963

It would be great to have "part=xyz" defined in ion-datetime element, to be more flexible for special requirements. Read my use case to understand what I e.g. mean

Describe the Use Case

I needed to build a date wheel like that, were user can choose a day within the next few days comfortable while showing the weekday.

I needed to do something like that for it:

<ion-datetime 
    presentation="date-time"
    [hourValues]="[]"
    [minuteValues]="[]"
    [min]="dateNow"          
    [preferWheel]="true" 
></ion-datetime>

And then put it do a container with overflow: hidden and margin top of -40px. That code is a freak of nature. I think it would be much easier to style it with parts. I could hide things and change height and so on.

Describe Preferred Solution

Add part= to parts of ion-datetime, to be able to style it from outside

Describe Alternatives

• More options for datewheel: A height and option to input date format or something like that
• Template parts to override ion-datetime parts with?

Additional Information

I don`t really get why you won`t let us style elements like that, or add template parts to add custom template parts.

I understand, that the idea is that you normally should not have to change the ionic elements, because you have a theme. But there will always be special things for some UIs, and it`s not a good idea that I have to install external component libraries with npm then only because customizing ionic components is limited strongly.

Thanks for the report. We have two existing feature requests for this, so I am going to close this ticket in favor of the existing tickets: #25945 and #25340 (The first issue seems to be more relevant to your request than the second issue)
