I know there a 1,000,000 regex questions but I have one I've been unable to find the answer too
In contentful (a headless CMS software) you can set validations for certain fields
Now I have set this regex
[a-z]+ to check if the string provided in this field is all lowercase letters (numbers and symbols are ok), but when I test it out, I am still allowed to use Capital letters.
Is my regex wrong? Or am I entering it wrong in this field??
