Disability on a 0-100% slider on a Spanish job posting site
The disability certificate goes from 0 to 100 and is given by the social security. Depending on your general or mobility percentages you get extra helps or tax returns that barely cover the extra costs from therapy or general help.
I see nothing wrong with that slider? They are quite literally asking you if you have an official certificate and its percentage so that they can get grants by contracting you.
