Cron editor for UI

Hi,
I wonder if someone found a good Cron editor to be used with Hangfire. I am stuck here: there is cron-expression-input component, which does not preselect the existing mask (so you need to start constructing the expression from the very beginning each time), also I can see some other controls outthere, but there’s another trouble with them - they support ‘Quartz’ format, but not ‘Hangfire’.

Sorry I have no input on a good online editor.

The format is explained very well on github: https://github.com/HangfireIO/Cronos.

I’ve used an editor for it before, but as you are pointing out they differs a bit from supported format, so I ended up editing they by hand. I suppose you can use an editor and tweak the string a bit.
