# A utility slicer for Power Bi
Assign default selection to this slicer by messures, just use DAX!
## Functionalities
* Implemented
1. Dropdown-slicer for text field
1. Use DAX to assign **single** default selected items to the dropdown-slicer
1. Support async slicers
* Planned
1. List-slicer for text field
1. Use DAX to assign **one** default selected items to the list-slicer
1. Use DAX to assign **multiple** default selected items to the dropdown-slicer and list-slicer
1. Range-slicer for number field
1. Use DAX to assign default selected range to the range-slicer
1. Single-date-slicer for datetime field
1. Use DAX to assign default selected date to the single-date-slicer
1. Period-slicer for datetime field
1. Use DAX to assign default selected period to the period-slicer
## Known issures
1. Slicer components for number field and datetime field are in developing, just slicer for text field is usable now
1. The outline setting has no effectivity on dropdown items
1. I can't change background-color of dropdown items
1. This slicer wouldn't support bookmarks
