Answer 1

• We should create a string list parameter which consists  of all possible flag values 

• Right-click on the parameter option and select show parameter control 

• And the create a calculated feild by using formula

• CONTAINS([Tag], [FilterParameter])

•  Put the calculated feild on the filter card and click the "True" box so that only rows that fulfil the formula above are displayed
