Hi Valentin,
Thanks so much for your report!
Yes, this is the expected behavior. There’s currently no code that would do the job. See: Global Variables Manager – Bricks Academy
- Bulk actions: …such as renaming and duplicating. … However, it’s important to note that renaming a CSS variable does not automatically update its instances throughout your site.
This is a similar limitation to this one:
WIP: CSS variable picker (dropdown) we cannot search for dash ( "-" or "- -" )
However, in my opinion, it makes perfect sense for „numbers", as it can always happen that you don’t want to select a variable and instead want to enter the value, the variable picker would still always pop up - which could be annoying in the long run (the logic is identical for every input/RAW value field).
But there’s a simple “workaround”: search for --900. This should work (at least in 1.10beta).
Best regards,
