Hi SL,
There are two Tab Switcher widgets. One of them, I created:
https://appstore.home.mendix.com/link/app/2964/
and for that one I can give you advice. The way to implement it for the scenario you depict is, that you need a context entity on the page button A directs to and that context entity should have an integer attribute.
When you click on button A, the integer attribute should be set to the tab pane you want to have opened on the tab container of your next page. This widget will read this attribute value -if instructed this way in the widget settings- and open the tab pane with the index corresponding with this attribute value.
For the negative scenario, just don’t set, or reset, this attribute to your default, when clicking on that button.
Thanks, will try that. What does one put in “Tab Class” using the tab switcher? Wasn’t sure what to put there. I.e., if my tab container has no CSS class that it needs, can I put any string there?
