I have one dropdown and one tagpicker field.
In dropdown all option's value are TagIds (like stockphotography:business/business_people).
I need to set selcted options value in Tagpicker field.
For classic UI i have done the same thing. But dont know how to achieve it in Touch UI.

Otherwise as stated by Scott, you can create a custom component where you can use TagManager APIs and can do the needful.
If you were able to solve the problem, can you please share the sample code snippet for the same?
We have TagManager API articles that may be helpful:

I want to do the same but in touch UI.
