Position additional menu tabs

I’ve made a few custom tabs on the menu, but I can’t seem to choose where they go.

On certain screens, they go over the date, as the screen isn’t big enough.
There’s also a big gap on the left.

If I use the following code:


OR this code:

It seems to render this code:


Basically, the system seems to automatically be assigning it a right and left position, and doesn’t let me override it. How can I override it, or choose a custom start place (20px instead of 211px)?

Terrace skin has inversive buttons positions, so it automatically convert position from right to left. But you can disable it by using

scheduler.config.fix_tab_position = false;

Thanks so much, that worked perfectly!
