Is it possible to make a floating worksheet/textbox (containing only text) appear centrally in a dashboard, above existing worksheets, when a user clicks on a worksheet (formatted as a button)? Can this be achieved using dashboard actions?
It is also necessary that this pop-up worksheet/textbox disappears when the user clicks elsewhere on the dashboard. Additionally, when this pop-up worksheet/textbox is displayed, it is required that the keyboard focus is on this pop-up until the user clicks elsewhere.
As of now, the help text in the dashboard is being displayed as a tooltip - and tooltips are not being read by a screen reader and that comes in the way of the client's ADA Compliance requirements. Also, we are using Tableau Desktop 10.2 and I've tested the screen readability using JAWs and Windows narrator - neither of them read tableau 10.2 tooltips - which makes charts and dashboards inaccessible to those with visual disabilities. Text-boxes, on the other hand, are read by screen-readers and hence this requirement.
I've attached a sample workbook mimicking the need.
