FYI: Parameter Actions are available since 2019.2

Today I’ve been on customer side where they wanted Tableau to have a filter which is able to

• select a relative date as well as 
• range of dates

Ideally this could be chosen by a Tableau Server Viewer interactively by having a simple switch between both. Due to the limitation of:

• this can only be adjusted within WebEdit/Desktop and
• there is no switch between both options for end users

I’ve been coming up with a workaround which might solves some of the issues end users do have out there. It would be great if you could reference this feature request from Tableau’s Ideas Forum. Any feedback to the solution below is highly welcome (positive + negative):
