scheduler inside tab

I am inserting a scheduler inside a tab
If I put it on the first tab, it is displayed correctly
If I put it on another one than the first one, I got it mis displayed
Only part of the first navigation line is displayed and nothing else
I have to click on this visible navigation line part to get the whole scheduler displayed correctly

I guess the scheduler is displayed correctly when I put it on the first tab because it is the tab that is displayed by default.

Thank you for your help

You can add a bit of custom logic to tabbar, and call

scheduler.update_view();

when tab with scheduler became active.
Above code line will force scheduler sizing.

(when scheduler initialized in hidden container it can have problems with correct size detection)

Thank you for your help
I worked perfectly
I ended up calling it with a bit delay:
setTimeout(‘scheduler.update_view()’, 10);
