I am trying to build a theme for our application, and we have chosen to build upon the material theme.
When I try to customize the look & feel of a DataTimeInput control, I am not able to change the Outline variant of that control as I am able to do so with TextBox input or Button controls.
My first thoughts was that most controls are basicaly input controls and the most generic of input controls is textbox. Changing the textbox's outline variant of the control, would also change the outline characteristics of the datatime or the dropdown control. But that is not happening. The result css does not include such changes. It seems that for other than textbox controls, the only available style to change is the flat fill mode. :(
Why is that? It seems to me that the Appearence options, of all controls, are important and should be available for customization. I cannot give a unified experience to the end user if some controls are customized to our liking and others not. Our UI/UX team choose Material theme and outline fill mode with medium rounding... they need to change the focus color of the drop down list control... and can only do so in the flat fill mode. Changing the textbox's outline, focus color does not change the outline focus color of the dropdown list or combobox outline.
