Hi Prince,
you can use a custom dropdown widget, and use the microflow as it's datasource, and there, you can use the Llistoperation- Sort option to sort the list.
Also, it would be better, if you apply a search option there in the dropdown, it also can be achieved through the custom dropdown. This way, your data will be filtered and it will be smaller in size.
let me know, if you have any issues,
Hope it helps!!
Hey!
Is it a reference selector?
If so use the sort property in the same, PFB
If youre using the dropdown widget kindly rearrange the items in the ENUM
They will be displayed in the same order
Hope this helps!
