Dummy div in a IWRegion

[StephB]

Hi all,
In my application, I have a blank IWRegion that I fill with a set of IWRadioButtons programmatically.
This is my code to create the buttons (I'm looping in a dataset to create several buttons).


And here is my HTML Template, that contains only one region for the moment, with some Bootstrap classes to display my buttons as a list.


When I open my form without any button created, everything is normal in my HTML source code.


But when I create my set of buttons, a dummy div is added inside my region to encapsulate my buttons.


This dummy div breaks my render because the flex-direction assigned to my region is not applied to my buttons, and I'm looking for a way to avoid a CCS rule like

Code:

#IWREGIONRELATIONSMGR_FRAMEADMINPANEL div {
  display: flex;
  flex-direction : column;
}

Any idea or explanation about how to avoid this dummy div ?

Many thanks for your help.
