- Create a string list parameter that contains all of the possible flag values (this is mildly tedious and can take a while if there are a lot of flags. It's usually better to populate this from an existing field or data column)
Right-click on the parameter and click "Show Parameter Control"
Create a calculated field as per the following formula:
CONTAINS([Tag], [FilterParameter])
Drag the calculated field on to the filters card, and check the "True" box so that only rows that fulfil the formula above are displayed
- Changing the value of the parameter control should then filter the rows as per the requirement
If you have any issues let me know, as I can give you the workbook that I used to test all of this out. :)
