Oracle APEX - switching Region Display Selector regions from a link item - oracle-apex

Question

I have a couple of classic report columns that are links and a region display selector with a couple of regions under it. How can I switch between RDS regions dynamically when a corresponding column link is clicked?
I tried setting link type to URL and set it to
apex.region("RDS").widget().aTabs("getTabs")["#MY_TAB_STATIC_ID"].makeActive();
But that did not work - APEX tried to go to a different page.

Here is one option. I didn't use page items but you'll probably be able to reuse the logic:
Create 2 regions, give them static id rdsregion-1 and rdsregion-2
Create a display selector
Create a static report with the following sql:
select EMPNO,
ENAME,
JOB,
MGR,
HIREDATE,
SAL,
COMM,
DEPTNO ,
CASE WHEN SAL > 2500 THEN '<div class="setrds1">set rds 1</div>' ELSE '<div class="setrds2">set rds 2</div>' END as rds
from EMP
Create a dynamic action named "Set RDS1"
Event: Click
Selection Type: jQuery Selector
jQuery Selector: .setrds1
add a true action to DA "Set RDS1" o
Action "Execute Javascript Code"
Javascript code:
$('#rdsregion-1_tab a').trigger("click");
Create a similar dynamic action for RDS2.
Note that both snippets work:
$('a[href="#rdsregion-1"]').trigger("click");
and
$('#rdsregion-1_tab a').trigger("click");
