I have two prompts on a single dashboard. One containing 10 attributes, the other containing 50.
If user selects "Clear All" (option beneath reset button), it only clears prompted values from one Prompt. How can I Clear all values from both prompts?
Can you add all the filters in the same prompt?
No. They must be separate.
Well .... That's no luck
Out of the box you don't have anything related to the prompt to "Clear All" all your prompts on the page.
So a way would be to use the "Clear my customization" button but it will actually reload directly the page.
You only other options (if you really can't put them together into a single one ... but you were clear on that) would to try to write some javascript triggering the actions of the 2 buttons, I just guess there isn't a little simple actions URL being the "Clear All" button but a bunch of events handlers and so ... good luck.
It will take you a while and can break at any update / upgrade ....
